BETA 1.15: Crash after clearing challenge mission

Challenge mission: cliffski’s challenge.

Upon completion of the challenge, the game crashed. (refer to image)
This was reproduced 4 times in a row.

This seems to happen after every challenge I try. GSB2 crashes just at the point where the challenge is completed.
