Bot crash when pressing Stop button #21

Closed steve1316 closed 1 year ago

Possibly found the reason why the bot sometimes crashes when the Stop button is pressed using the Flipper debugging tool. Also need to implement solution to the framework as well.

Closing this issue for now. Have not encountered it since and there had been major revisions to the underlying framework since then so this is probably fixed by accident.
