Love Heartharena to death and this app is amazing when it works. I think its just Overwolf though. Theres a good chance if you stop during a run and come back itll be gone completely, draft and run, even from Heartharena itsself. Recently I tried (several times) to start it up and Overwolf keeps saying "Opps! something went wrong, click here to restart" or something to that matter. And earlier I tried it, and it failed to talk to the HA server, it stayed on "Evaluating pick#1..." even after restart. I tried updating Overwolf but that wasn't happening.
