kenshi has burst

[bertex]

I have been playing the same game for several months and out of nowhere while I was returning from an exploration to my house passing near bubble hill, it tells me that my kenshi has burst and to publish in this forum

Looks like a corrupt overlay file.

If you have the game installed via GOG Galaxy, you can go to the folder below, delete all files inside, then validate/repair the installation.
Kenshi\data\newland\land\overlaymaps

If you have it outside of GOG Galaxy, you'll likely need to reinstall the game unfortunately.
