Should've mentioned it in the op, sorry.
I am in the default 1.3 branch.
Edit: Turns out my game did not update to 1.3.1
After selecting 1.3.1 manually and updating i was able to login but now i cant get into the custom deathmatch servers as it freezes and crashes after loading the map. The team banners are all white and the timer is at 00:00
I should test that a few more times to see if it is temporary or not though.
