FireTarget wrote: Well like I said before, other mobs (even vanilla ones like Creepers) CAN destroy the terrain, so mobGriefing happens to be enabled. I replicated this issue in Survival as well as in Creative mode. I've even done a clean reinstall of Forge and this mod and the issue is still there. I would appreciate it if someone else could try to replicate it as well to see if it is a problem on my end. If you are testing them in creative mode. Exp: spawn a mordor bombardier and a hobbit. They will not damage the terrain. If you hired a bombardier, he'd bomb will do damage to the terrain, even bombs you give him such as 3x power fire bombs.

If you were in survive mode and they try to kill you, they will do damage to the terrain. If a area is protected by banners, they will not damage the terrain. If you were +1 or more with them, they will not damage the terrain.
