Describe the bug
・If you or any other mob is in the multiblock construction area, it will suffocate once the multiblock is built
this is especially problematic with the cleanroom controller because the 3D builder builds plascretes at the side toward the player
・You can perform Automatic Build and Debug function even if the multiblock controller is broken by other thing such as Wither
・Open GT Console App when the 3D built multiblock is being destructed by wither, then try to open 3D Builder again, the game crashes

Expected behavior
you can't use 3D Builder when the multiblock controller no longer exists

Clips

・you can place any block above the water source with 3D Builder
・you can place some blocks should not be placed with 3D Builder

Does the crash still happen? I can't seem to reproduce it.
