Some of these rewards seems to be tied to lots, and not to sims..the no bills ever is one of them for sure.
I'm looking for a way to make it *work*, again. Both my sims have that reward, and both live under the same roof. I went to Edit Town and move lot, just so I can replace it down on the same lot. (I never found another way to turn a lot around)
The game obviously sees this as a new location, and my sims started receiving bills again. I cannot buy the same reward again once it was acquired...so what can I do about it?
There is no way I'll wait for one of their 5 kids to pile up 15000 point so one can buy the No bills ever reward. I'd rather have them spend their own points on something more suitable for them.

Do you have NRaas MasterController? Maybe you could use that to remove the reward and add it again? I believe that should be possible. Not sure if you need the Cheats module of the mod, for that functionality, though.

I have MC and the cheat module. I'll figure it out, thank you!

There is a bug in MC with that function, though: dropping an award will give you back double the amount of points you spent for purchasing that reward.

* Suddenly thinks bugs aren't that bad...
By the way, talking about points...is it possible for a sim to gift points to another sim, from their own stash of course?
EDIT :
Well, good news is..if it is one, my sim only got 15000 points back, dropping the No bills ever reward. Looks like the bug is gone.

As far as I could tell, to give LTH points to another sim is not really within the game function, but with Master Controller and Cheats, you can mimic it.
Cheat to add points to the recipient. Then cheat to subtract points from the donor.

I know that it has been 7 years since a reply was made at the time I am writing this, but on the off chance someone does see this… how do I drop a reward?

Once bought, most rewards become hidden traits.

I don't have the game fired up right now but with Master Controller + the cheats module, it's under advanced -> traits -> change (if I remember the path correctly) when you click on the sim. Once there you scroll down through all the traits and click on it to deselect it. I'm not sure what happens in the code but that will actually get you double the points back (like if you have attractive for 15,000 points and deselect the 'attractive' hidden trait, you end up getting 30,000 lifetime happiness points back) but that can be corrected with Master Controller too.
