I made a new profile with autosaving off from the start and I was somehow able to finish event 3 (which is one of the rally events which froze up before). I also didn't touch any assist settings before the event (doubt that did anything, but who knows).
Woo! Will keep driving til the wheels fall off!
-edit- Hah! I turned assists off again when firing up event 1 (the other rally event) and it froze as usual.
Freezes related to turning off assists? What in the world is happening?
-edit edit- Tried the event again with assists at their default. Still froze. Did I just run into some weird fluke before? I'm so confused!
