[0.17.67] Crash in editor: Unknown enum value: 6

[killerlink]

Game suddenly crashed, will try to provide as much information as possible.

Happened on my design test map, originally created through single player menu, switched to god controller, and enabled editor with "\editor".
The last thing i was doing was trying to find out how to effectively delete biter areas using the editor. I think i tried several of the menues and i *think* i was on "Tiles -> Area" setting and tried around clicking mouse buttons when the crash happened.

Please see attached log, which indicates the error message "Error TileEditor.cpp:624: Unknown enum value: 6"

Edit: Can reproduce bug reliably. After I load the Save, in the editor menu i select "Tiles", "Area" and right click a biter nest. Screenshot shows game moments before the right click.

Can reproduce: load a 0.17.66 map -> /editor -> tiles -> area -> right click any(?) entity (I got a crash right-clicking my own locomotive)

No stable for me this week, I guess
I hope you do organize the student's council's party so I can drink my frustration away
