Editsim <simname> seems to be borked. After you make the changes to a sim and press the checkmark button (which usually redirects you back to the game), nothing happens. You are stuck in CAS and cannot exit by any means except closing the game.
that has happened to me if the sim (townie) I was about to edit was about to go to work and had their uniform on. (=not smart to play around with this on sims that aren't in the current household.)
Those people also had the problem. I have left it for up to half an hour, and it still won't work. It happened randomly before I installed Fast Lane stuff, but mostly worked. I got the most recent version of awesomemod, and I update it whenever I get the flagrant system error that it's expired. I used to never have problems at all with editsim, that's why I'm so confused.
