lastException.txt Files and You
In your game, if you have MC Command Center, you might see an orange lastException notification. If you don’t use MCCC, and something odd happens in your game, look in /Sims 4 and see if a lastException.txt file is there.
Sometimes LEs are caused by core errors. The best way to “fix” those is to avoid them. Change an item’s location, or use a different item, that can help, depending on the error. Deleting the localthumbcache.package file out of /Sims 4 can sometimes help with these kinds of errors, also.
MOST lastExceptions are caused by old or broken mods or cc (custom content). Depending on what EA changes with a patch, this can break script mods, package mods, or both. UI-based mods are very likely to need updates following ANY EA patch. Script mods USUALLY will, also.
CC isn’t affected as often, but, it DOES happen, and it did with the 1.30 June patches. If you’re going to use mods, you need to check those after each patch. CC generally depends on what EA does.
These Exceptions are just text files. Don’t be afraid to open one and see what it says. Sometimes, they will tell you exactly what mod or cc file(s) just blew up on you. Usually, they are not that forthcoming, though. They ARE hard to read in their “raw” format, though, but here’s a website you can paste it into that will make it easier to look at: http://xmlprettyprint.com/
If it tells you something useful, remove the mods or cc files it lists. Delete the localthumbcache from /Sims 4, and try your game again.
If you can’t figure out what it says (some/most ARE pretty obscure), we recommend doing the 50/50 test, detailed here:

If you play with MCCC, we add a couple of things before you begin, though.
We tell people who visit our MCCC Support Discord for help to first either put a copy of their save file on the Desktop, or roll a Save As… test copy, then, quit the game and remove EVERYTHING from the /Mods folder, except for MCCC and the Resource.cfg file. Delete the localthumbcache out of /Sims 4, and then test your game.
If you don’t see errors, now you’re ready to either do the 50/50 test, or start dropping folders/files back in for testing, depending on your /Mods folder organization.
If you put a folder in and get an error, I would take it back out, put it aside for now, and try it again AFTER you have all the files you want to play with loaded back in that do NOT give you any trouble. You may end up with just a few things you need to test further.
You should check the download sites for your non-working mods/cc, to see if the creator has posted an updated version. If no one else has left a message about it causing trouble, and it has not been updated yet, they would probably appreciate being informed, nicely.
