Tummy Time not working

Every time I try to do the "Tummy Time" Interaction my Sim and infant reset. I tried removing all mods and deleting the localthumbcache file. It would still reset despite not having any cc/mods installed. The odd thing is, I tried the interaction in a new save file and it worked fine. I've been playing in the same save file for 4 years now, so I don't want to abandon it and start a new one. I would really appreciate any help. 

And I just checked, adding all mods back in and trying the interaction in the new save file works fine. It seems to only be an issue in the old save file.
