Re: Sims Cannot Perform Directed Actions
If you've had no issues after playing for a game week, then that should be enough. I usually don't go that long, just a day or so most of the time.
There are a few ways to test for mod problems, but like you, I only run a few mods, so I test mine one at the time first, then test them a few at the time together, and finally all of them together. Most of the time I usually have a good idea which mods might be acting up based on the problem I'm having so I test those first. Sometimes, a problem is not a broken mod, but is caused by two mods conflicting so when you test them one at the time, you find nothing wrong. So, testing them together is the only way to find a conflict. Before I test anything though, I go back to the sites where I got them and make sure I have the latest version of the ones I have just to make sure I didn't miss a mod update after a game update. Then I start testing. I always start with my older mods too since it's more likely that they might break as new game packs are added.
For CC, I check everything that I add with Sims4Studio (S4S) individually before I add it to my game now. But, when I run into a problem that I think is CC related, I'll look at everything I have again just to be sure. If you have a lot of CC though, that can be impractical so the 50/50 method is the way to go.
Hope this helps.
