Kerbal Space Program

Not sure exactly what happened here, but I had allow objects to overlap in the debug menu and this seems to have happened. It's a bit hard to explain in words but basically I have two craft files I'm including, one hangs the entire hangar controls when you load it. The other one will hang if you try to fix an error in the craft. Note, the game is still going, the interface is what hangs.

I noticed when I went to launch my ship after a modification that one of the engines is underground and firing. I thought I'd made some part misplacement so I went to check and discovered there is a duplicate part occupying the same space as it's intended counter part. If you try to fix this, or delete a part, you will no longer be able to interact with the craft in the editor. Note, I'm using some modded pieces; Improved Struts and Trusses, KSPX and Damned Robotics. Since I can't edit these files, there's nothing I can do about that. I figured I could just pop it open in a text editor and see the issue but it's all greek to me.
