About an hour ago I was playing fine - when I tried to restart steam kept telling me it was unavailable then finally it started the launcher and now I get an App Crash when I hit the play button.

I've deleted all mods and mod files and unsubed from them all and it still App Crashes. Rebooted, same.

Try verifying your game files.

Getting the same thing.. Just got the update and now I cant run more than a couple of minutes without the game completely freezing..

Also did a cache verify.. Still crashing after maybe 5 minutes.

Try allowing the game to identify the best graphical settings when you start the game and see what happens.

I've experienced zero crashes with 1.4.21 or 1.4.27, but I don't use any mods. Make sure any mods or plugins you're using are up to date. If you still experience crashes, try removing mods to isolate the problem. The update is not causing the crashes.

*facepalm*

I don't know why I didn't try that first. Thanks. I'm all set.
