AI being BAD and sims need reseting alot

I'll contribute my problems with highchair to the latter, thanks!

I currently have only one household that I play and just moved them to a new lot. I can't remember the sims stopping and getting stuck happening this much before, but it has been happening from time to time, always. I haven't figured out anything that would connect these cases as they happen in different rooms, different times in completely random situations in the middle of task que. Yesterday it was first a sim who was live streaming his music mixing and got stuck after ending that task and never started anything new from task que (until I used resetsim). Second was a sim eating. I don't know why he stopped eating but after putting the plate away they got stuck and needed resetsim to start functioning again.

I maybe need to play a bit more to see if these sim freezes are in any way related to the toddler-obsessing and high chairs... I'll probably first get rid of the high chairs and see where that leads.
