Scattered Stones is a mod that spawns rock filth beneath the stone chunks that spawn on the map, so yep, if that mod encountered an unexpected error caused by Rimkea's patch, it might have upset the terrain bitmap that gets encoded into the savefile. Depending on how "late" the error occurred, that might be what caused Sandstone to turn into null tiles while still allowing Granite etc. to spawn normally.

Hello
In reference to you post regarding rimkea destructively patches stone chunks, does it affect all stone types?
Have natural sandstone walls( only sandstone walls, grantite and marble in map are fine) suddenly gone/counted as undiscovered areas.
Shortly before that big problem there was some error regarding ScatteredStone.Rocks.

Thanks in advance.

Isn't it great how after spending several thousand dollars over a span of about four years, they decide to give you basic features that they should give to everyone for free?
