Potty training causes my sims to reset and cancel action

I've been having an issue for a while where if my sims (an adult or toddler) try to initiate the potty training action they'll go into a quick t-pose reset and cancel the action from the queue. All animations are typically able to be carried out (sometimes during the talking portion before potty training the toddler and caregiver will stare into space until the action is cancelled), but it's always right before using the toilet that the reset happens. The issue is reported as a constraint issue which could be due to the amount of objects on my lot in my main save file, but the same thing happens in a new save in an unfurnished house. I get this error following a couple of other actions as well, but the potty training one is the only error that happens consistently. I've cleared out any broken or outdated mods I've seen from BE and MCCC reports, but the issue still persists unless I play a reset game with no mods or save files. I don't want to have to build my save completely over again, especially since I've used MCCC to expand the size of my househould and wouldn't be able to save them to gallery for a new save.

  • Hi Mimo_rock​ 

    you say it doesn't happen with no mods/save files. Does it happen with no mods on a new save file and does it happen with a copy of your save with no mods/cc ?

    I just tested it to make sure and it worked for a second on a new save file with no mods, but with my past saves and repairing the game before starting. However when I exited and came back the same glitch happened.

    Do you still have any LastException files in Documents\Electronic Arts\The Sims 4 ? Please post the ones you get on the vanilla game

    • Delete the ones you have
    • Trigger the error again
    • Check if new ones are created
    • If that is the case, please copy/paste the content here. You can open the file with any text editor.

     

    Deleting the file won't fix your issue. Posting the info is meant for troubleshooting.
