I found this while trying to figure out why only one of my saves (my Riverview one) crashes about 5 minutes into loading, and I haven't been able to play them since sometime in May and it's July now. It's the only one of my saves that crashes.
I ALWAYS delete all the .cache files (social, simcompositor, script, compositor, caspart)
I ALWAYS delete Collections, Custom Music, Exports, Featured Items, IGACache, SigsCache ... I read that those were the ones okay to delete
I ALWAYS make sure the CurrentGame.sims3 is empty
Off and on I delete the Travel.DB from all of my Saves (memories are a waste)
I make sure DCBackup is empty except for ccmerged
I have a TSUNAMI of 3rd party content, but I run Delphy's Dashboard from time to time to check for corrupted or conflicted content. If anything pops up I delete that content. As of right now, it says everything is fine.
I don't think it is Mod related though and maybe a problem with Riverview since it is only that save that crashes?
I am going to try and hopefully save my family to the bin and reload them in Sunset Valley or maybe Twinbrook....I have had very few issues with Twinbrook.
To save the family to the bin I go into Edit Town, right?
Also I may try doing resetsim * as that helps with freezing in a few of my other saves...maybe will help with crashing in my Riverview save.
