Recreation:
- Host space age on headless server
- Join game from windows client
- Make blueprint of something
- Set to snap to grid
- Set to relative snapping
- Set height or width to 0
- Set to absolute snapping
- Client crashes instantly, server is fine
- On client restart->rejoin, blueprint is still open to be edited with snapping turned off
