This is the error according to the debug:

2022-05-22 09:48:36: ERROR[Main]: ServerError: AsyncErr: ServerThread::run Lua: Runtime error from mod 'glider' in callback luaentity_Step(): .../staging/worlds/world/worldmods/glider/init.lua:47: attempt to index local 'driver' (a nil value) 2022-05-22 09:48:36: ERROR[Main]: stack traceback: 2022-05-22 09:48:36: ERROR[Main]: ...staging/worlds/world/worldmods/glider/init.lua:47: in function <.../staging/worlds/world/worldmods/glider/init.lua:10>

Just saw a server crash due to this same thing. Not good that players can crash the server on demand as this can lead to protection bypass exploits.

I came up with a patch and opened a pull request
