Crash: Close review window when bot is in self play to reproduce

[bjordan2010]

This might be low priority and I don't know if it can be handled more gracefully but it happens every time if I close the review window while the bot is in self play. If I close the self play tab first then it doesn't happen. Might not be important but figured you should know.
