In that case I’d urge you to follow the last part, better yet record a short video ever time you click the coin then go to your log, couple of seconds every day until you can show that a bug happens on the chrono side of things. They’d be real happy with your help I’m sure.
Because once again I must say even if there is an actual problem it is impossible to fix it until there are any sort of visible traces of it.
