Undefined transition errors?

[Austere]

Between CAS and moving a Sim into a lot, I've been getting them ever since I allowed CC to be enabled in my new Apartment Life. I'm now looking to see if all of my hacks and stuff are updated, but I'm not sure what to do since there is so many of the errors being thrown up. I looked in my error logs, and saw that almost all of the object errors had something to do with Inteen, but I can't be sure. I'm getting it right before CAS starts up, and multiple times before a Sim moves into a lot (which doesn't work - the game will either crash or I will end up in a lot without Sims).

Is there something else I can do to make sure this problem is gone completely?

It sounds like you already know what you need to do.

Update all your hacks and/or CC. If the problem persists, do a binary search until you locate an error-generating item, remove it, and see if that fixes the problem. Repeat until the errors go away.

I think I solved the problem. I took out my hacks folder and everything was going swimmingly. Now I have a slightly complicated question. Since AL is the last expansion pack, would I have to keep updating my hacks if I were to install Free Time or something later afterwards? I keep hearing people talk about how their hacks go weird if they don't install the games in order. But here's the order my games are installed:

Double Deluxe
Pets
University
Apartment Life

Nope. Latest expansion pack determines which Director's Cut to use. If you use AL/MGS, you use the AL DC.
