Should i reduce my big household which has 15 kids 2 pets and 2 adults the time moves nornally expect for fast forward which does nothing. It takes a hour and half too 2 hours sim time to unload the school bus Was just wondering if this lot would play ok with seasons as won't have insim for while after to remove them thanks for anyhelp

I'm not sure how the game handles these households that are over the game limit when you remove the hacks. It might crash, it might be alright. Maybe you could play another family until the hacks are updated?
In any case, never ever keep those unupdated hacks in your downloads folder when playing a new EP.
For any other people who wonder how to get ready for a new EP:

Please, please, read through those and don't come knocking for help if you still have hacks in your downloads folder!!!
Okay, you may come knocking for help, just don't say we didn't warn you!

Make an experiment. Make a new neighbourhood, a new home, and add to it a number of random useless sims, beyond the limit. Then remove the hack, and check what happens. (by the way, tell us)

I took out insim and other hacks lot loads fine other than everyone being outside when it loaded it so i will run with out insim till it is updated for seasons

Great to know! Thanks for testing ticklish
