hey guys so a few days ago i was removing mods that conflicted with story progression. after i removed them and went back to playing, my pregnant sim won't give birth. right before the baby is born an error box popped up and if i press reset, the sim in question stuck in an animation loop. tried using whatcausedthis and it said i missed some important mods. but i already have them in my mod folder. i asked on the lazyduchess discord server but not even people there know what's wrong

i tried moving the pregnant sim on an empty lot but it still persists, and im using sims 2 rpc launcher so technically i do delete the cache every time im playing

im honestly ran out of solution at this point

Post the error log, someone may be able to read it.

Might be time for a 50/50 search.
Make a back up, try without CC-does the birth go normally? if yes its something in your download folder and sometimes the only way to find that is cut it in two and place one half back in your game. Does the birth work now, yes or no? If yes, put that half on your deck top and try the other half. Then you take the half with the issue and cut it in half again and test each side of that. You do that until you find the problem file.

Now its also possible its the action of two files together but I would at least try a 50/50.

Bad Gosup tree is normally caused by a mod looking for and failing to find an extra file as what caused this suggested. That does list the major ones but there are possibly more.

You said that you removed some mods that conflicted with Story Progression. Is it possible that one of those mods was affecting the pregnancy and it's now trying to find it? What happens if you put those mods back in?

Yes, their image shows that they already have the listed files in, so it's either a gameversion issue or another mod that has a dependency.

They have all EP's and SP's listed on their profile, I checked. So unless they don't have them all installed it shouldn't be a game version issue.

i could try that but those mods were also causing error ingame, and thus what lead me to remove them in the first place

yeah it looks like i have no other choice at this point but man i hate the 50/50 method because it's so tedious. I'll do it for real if there's really no way to solve this

Oh! You have NoSimLoaded? I wonder if this is the problem with the pregnancy tokens that is known about (see this thread for example: https://modthesims.info/showthread.php?t=646976 )?

@Kestrellyn might know.

No Sim Loaded only throws a birth error if they don't have Smarter EP Check, but they said they have that.

OP, how deep are your folders? Could it be so deep its not being read?

This isn't the No Sim Loaded issue. "Bad gosub tree number" basically means that the game is trying to call a function that doesn't exist. Usually this happens because you're missing part of a mod, or, as the message says, a global support file where that function is defined, which is why it shows you that message. It doesn't necessarily mean that the problem is that you're lacking one of those specific files, you could be lacking a completely different file, those are just the most likely culprits, so those are the ones that were included in the message. It could also mean that the missing function is in an expansion that you don't have, and the mod you're using is expecting you to have that expansion installed and you don't. The function this is happening in - Prepare New Baby - is now being modified by a rather large number of mods, at least one of which you probably have installed. My best guess based on this error in this function is that you have a birth mod from MidgeTheTree installed and are running the Super Collection or otherwise don't have AL or M&G - unfortunately, Midge doesn't seem to have made any of her mods compatible for people without the UC and also doesn't advertise that her mods require AL/M&G when they do. In AL, there is code in that function that temporarily removes a witch's special witch name so that the new baby doesn't inherit it, and obviously if you don't have AL, you don't have the function that does that, so you get this error.

like 2-3. it's that too deep?

Ah, I was thinking that if a token was deleted, that could have caused the function to miss, but thanks for the explanation! Shows how much I know.

@HanaHana543 Do you have all EPs and SPs?

Yes i do, this is what it looks like in my file manager

There's no restriction on how deep your folder structure can go, the only issue is that if the full file path is more than I think 255 characters long the game won't be able to load the file at all. But then it would just appear like one of your mods was not installed, or not working.

What birth mods do you have installed?

Yeah, I don't mean to put them back in permanently. I just meant put them back in and see if that lets you give birth, then take them out again. In case the pregnancy was using one of them.

i have these


(though i don't trust the search feature because i feel like i have more than these, i just don't know the mods' name)

im skimming the mod folder as im typing

"Birth mod" doesn't mean that it has the word "birth" in it, it means that it has something to do with when babies are born. Do you not know what mods you installed?

Okay I'm Back From Doing 50/50 And Finally Found The Source Of The Error

turns out your surrogate mod is what causing the error in my game. which is weird because before i removed the mods that were conflicting with story progression it works just fine, and the sperm donor mod still works. sad to say even though i love your surrogate mod, i decided to removed it.

seriously you have no idea how many of my gay sims you helped with that mod alone

you guys, thank you so so much for trying to help, without your clues of what could cause the error i probably would've still stuck by now

i stopped playing for a while because of that specific error, and i'm back playing ts2 again i guess. i hope this thread could help future simmer

and my sim gave birth to a baby girl

@HanaHana543 What was it? Don't leave us hanging.

Edit: Reading up. A surrogate mod? I don't know it. I went hunting.
https://modthesims.info/d/658001/surrogate-hack.html I assume. kestrellyn should be able to help with that.

The only way the surrogate hack would match up with the error log you posted is if you installed the baby personality version without installing the baby personality hack.

By the way, the surrogate hack will also cause problems with story progression, just like every other birth hack does.
