Users use the undo action as an extra ability

[UNiXMIT]

In the majority of my games, the opponent uses the undo action on cards that have just revealed my hand or revealed some information that they shouldn't know about if that hadn't played that card. It's giving them an extra ability that should not exist.

Either that undo feature should not be allowed when certain cards have been played that reveal information they cannot "undo" from their memory OR there should be an "I agree" button so that both parties have to agree to the undo action.

Thanks

Ah OK I see there is a 'Request-Undo' game mode. Thanks
