[1.2] Crazy broken world map bug

[slime.exe]

Hey everyone,

I have hundreds of hours into one of my playthroughs, haven't changed any of my mod settings, but today I noticed a weird bug where it looks like my world map is... well see my attached image.

It's not just a graphic bug though. Many of those black tiles are now "ocean" tiles. And if I use a shuttle to travel to another settlement, I get a message that says my caravan arrived with no colonists on it and so my cargo has been lost. Every part of that shuttle caravan disappears, colonists included.

I'm not sure what caused this, but I'll do whatever it takes to save my colony! Please help me
