Here are is a log
2018-03-07 18:30:06,445 [34] ERROR BotManager - [Stop] Exception during execution:
GreyMagic.InjectionDesyncException: Process must have frozen or gotten out of sync: Injection Finished Event was never fired
Something on your system must have kicked on at the time and caused the game to stop rendering. Screensaver, power saving, or some 3rd party overlay most likely.
There are very few places where the bot could actually crash the client, but certainly not in the middle of the code that was executing in your log before your client died
[PlaceItemFromCursor] Now going to place "Scroll of Wisdom" from cursor to {2, 2}.
Also, if some effect in town caused your client to die, that too could be an issue, and would have nothing to do with the bot running at the same time.
