What I did:
Clicked on a filter miniloader that for some reason had stopped working, tried to rotate it (R hotkey) thinking that it pointed into the wrong direction.

What happened:
Error message displayed, game closed. Remote player got "Server not responding".

Error message:
Error while running event miniloader::on_player_rotated_entity (ID 21)
miniloader/control.lua:169: attempt to index local 'miniloader' (a nil value)
stack traceback:
