I had Light Sliding Doors placed on my ship and and hooked up to proximity detectors, and then after a while one of them wouldn't let me walk through. I deleted the door and tried to replace it but it wouldn't let me place anything where it was. Now I have the collision of the closed door but nothing is actually there. I've tried placing blocks on it but it thinks something is there so I can't. I've tried using bombs to blow it up but they don't work. I've tried replacing the proximity scanners and hooking them up but the door's wire node is gone, obviously. I've tried placing background blocks, painting, deleted, etc. and nothing changed anything. I've tried upgrading my ship, it replaced the background tiles but the collision was still there. I've tried reloading the client, reloading the server, restarting the game, and nothing changed. I've tried spawning liquid blocks on the affected area but it wouldn't work. The matter manipulator understands that collision is there because it allows me to hold left click and I hear the popping noise but it never breaks. Held it for about 1 minute. There are no useful admin commands for dealing with this. Here's a screenshot: Please help.
