So I was shaman in the ball pit map, and I cannoned the balls and the cannon went straight through.

Any help? .-.

What map code was it? Was it a Vanilla map?

Yeah, same thing happened to me, lol, I spawned a cannon and it went through. I spawned a second time, and it didnt go through.

I do believe the issue you're having is related to this.

HHHHHHH. The ball pit map I think your talking about, Aqworldsx, is map 11?

I think this is a feature.If you go in survivor room, there is at least one map, where every objects the shaman summons, can go through the grounds.

It's different, just read this thread Topic-541904
