Firstly, thanks for replying to my thread Dannamoth.
Secondly, I'm not sure which games I had the error except for yesterday (happened in one game - playing Draven) so I'll just post that log and will update this when/if it happens again.
Thirdly, I'm pretty sure this happens only, or more frequently when I play Draven.
EDIT - 21st sept, 11:11pm.
Bugsplat twice every game tonight (3 games). Won 2, lost 1. Makes me sad.
Played another. Bugsplat 3 times.
Okay so I played another two games after these ones, and I didn't experience the bugsplat error in either...
