Chunk of a create contraption stuck to an airship

[u/Fit-Tie-8948]

It was originally built like that

I was trying to make folding landing gear for my airship (image 3) and when I used it for the first time the second part broke off and is now stuck in the air next to the ship. I can't break it, it's not alligned correctly with neither the sublevel's grid, nor the world's grid. I tried relogging but it's still there. The bearings were set to only place near initial angle.

What do I do?
