Thx. Appreciate the info.
I’ll publish a bug report discord with the next release.
That’s a weird one. Saw it once before with a corrupted savegame.
It’s not reproducible and should not occur on a clean 0.4 game/save. I added a few more paranoid checks in version 0.4.1 which is out since 16.06. on patreon.
Public release in two weeks or so.
