What happened to get you banned? If you post in the thread I link below, we can see which admin banned you, and their take on what happened too. https://forum.kag2d.com/threads/beos-kag-servers.1273/
If it reaches the top of the map, then it can collapse but you'll be safe, as the top of the map supports blocks. If it was right at the edge of the map, then zombies can't get up there anyway, because they die upon contact with the edge.
I've un-permabanned you for it, but until I've heard from Schizoid I've just put you on a temporary ban. It's only 1337 minutes, so it's just under 24 hours.
