I realize that mod seems abandoned, but still gonna leave this bug report here as a warning.
Symptoms: a ghost character entity of name "entity-name.fatcontroller" has appeared. Interactable, with an inventory and equipment slots.
Saving and loading didn't make it go away. Disabling the mod and force-loading the save helped.
Migration log was : Removed Entities -> fatcontroller (character) -> 3.
Possible way to reproduce: attempted to control a train on a surface different from my character's, using SE's navsat mode.
