okay game just crashed on me, I think this is the same failure. Events leading up to the failure:
1. Join 4 player lobby, I was player #3, the other two were finishing their match
2. Player 4 joins, the other two finish their match and all 4 of us Ready Up, I get paired up and we go to Char Select screen
3. I select my Entourage 1, the other player just sits at the Team Size selection, so they may have crashed or something here
4. My match closes and I'm back in the lobby, player 4 is missing, and the other two are once again finishing their match
5. Now there's only 3 of us, the other two finish their match and we all Ready Up, since there are 3 of us now, I became the Spectator
6. About 5-10 seconds after seeing the 'Spectator' notice, Skullgirls.exe crashes and I get sent back to my desktop with the Windows error saying Skullgirls has stopped working
So when that happened, I had to imagine it's because one of those guys ( or both ) were selecting an Entourage, since i was waiting for them to choose teams when my game crashed. I was running Skullgirls Retail with the '-log' start parameter, but I honestly can't find where the logs get dumped. I do see what look like crash dump logs ( *.mdmp ) files inside "C:\Program Files (x86)\Steam\steamapps\common\Skullgirls" , but the latest is dated a few days ago.
Let me know where I can find the debug log and I'll post it here, as well as any other details if you'd like.
