It's not the first time, but I have forgotten my hero was immobilized. And this time I moved him to push a door, there is no backspace/rollback button to undo my progress... how can we get a hold of the devs?
The app's status is saved at the beginning of every new round. If something like a door was opened accidentally, I think the best (current) solution is to kill the app and reload it. You will end up with slightly different random variance in combat and activations though, so the choice to kill/reload will want to keep that in mind.
