Hi Micha, looks like it works for some of the drones (one in my case).
Maybe the save file is corrupted? Attached the Saves folder, if it can help.
Saves.zip
"Toggle center of mass" gets reset (to off state) whenever switched to another window. The opposite is true for "Toggle editor hotkeys" (off to on).
Other toggles are unaffected ("part overlap detection" and "tag bindings").
Not sure if this is a bug or is intended to be this way
