Pretty much as described in the title; updated from the beta patch to 2.3 and now the game refuses to load. I'm not running any modifications, I've verified the integrity of the game cache without any issues and I've tried running it without DLC as well. I'll give it a shot by reinstalling the game, but at the moment it just doesn't seem to want to load at all.
Oh, and it crashes on 'Processing Flags...' on the load screen. I'm not sure if that's useful to anyone.
EDIT: Tried reinstalling, still falling. Deleted all of the files on my hard drive and reinstalled again, failed again. What the hell?
I'm going to assume this is an issue with my Mac then, seeing as the patch is running fine when I boot up my PC. That's largely disappointing.
Checked this out on a mates PC and Macbook as well; there's definitely something wrong with the Macbook version of the game at the moment. At least for us.
