i keep getting "this may be version mismatch or a missing mod. deserialisation error! this contraption is incompatible, this may be a verison mismatch or a missing mod" when flipping anything that has activation like guns,machinery and for some reason anything that stabs.

I tried looking for anything on the web on how to fix this, but i found nothing. I tried fixing this by uninstalling mods with errors, nothing works!

also another thing, mods that contain tools that attach and put together stuff like ropes, cables and wires disappear when spawned in so buildings just collapse.
