For some odd reason I can't place the two cloaking devices, but, I can place both the panel block and the block spawner. Did I do something wrong?
Edit: I can only place them in specific locations. For example: a location where there aren't any braces. Weird!
Edit 2: For some reason the intersection warning is removed. This could have been caused either by the mod loader or the building tools.
Edit 3: It's caused by spaar's modloader, so, ignore this entire post as I just found the problem.
