Seems like the punishment was kind of deserved, it's not the first time I've seen some bad movements from Polarbear so it's kinda easy to believe this could've happened. You must be sure cells are open before you proceed, you can't just make a guess mate. On the other hand, a warning kick/rocket could've been issued in the first mistake of the player instead of a 2-hour ban because, you know, such things can happen.
Anyway, the ban has expired and the report is not strong enough to prove the admin has done a noticeable mistake to take action.
Dropped.
