I've noticed a glitch in Rock Forest and Lost Ruins Reverse, where the cycle will be stuck at a max of 5th gear, losing probably close to a minute on each track. Is there any way around this bug, or any way to correct it?

I'm not seeing anything in the rules that states we need to create a new character for the campaign runs. Can we get some clarification if that is necessary, or if we can play on the same character over and over?
