In Moviebattles II (a full conversion mod for Star Wars Jedi Knight Jedi Academy), I occasionally experience random crashing while playing online. So far it has only happened while I'm alive in-game and playing as a Sith or Jedi, but I'm not sure if it could happen at other points too (I don't play as a gunner that much). I'm using the Moviebattles II client, and Steam Integration is turned off (it was always buggy for me).
Here is the log in case it is useful. I am using Windows 8.1. The game used to work fine for me but in the past 4 days or so it has started crashing. Is there a fix to this?
