[crash bug; 4.0 beta] Crash log - every time session ends, after collectibles

[BlackjackGT]

I suspect devs have flown the coop, but just in case they still exist, here's the crash log text every single time I finish a session, and then review the collectibles. Then it always crashes instead of taking me back to the main menu. Could be old news.
