I'm playing with Biomes! Islands, and when it converted to an island biome, it flooded the entire map with deep ocean tiles.

Edit: The land does come back with the next change though, so it's still theoretically playable if you prepare.

I was playing on a tropical island from "Biomes! Islands" as well, when biome change event happened. As soon as the edges of the map became sand and water was cut off from the rest of the world, all the fish had nowhere to go and started spamming the console with errors connected to pathfinding. Is it possible to exclude water surfaces from changing/disappearing?

Ran into a small problem with Advanced Biome's Volcano biome. The lighting effect from the lava stayed on the map, even though the lava was completely gone after the biome changed to a Desert. Any way on fixing this through xml editing?

Had an NullReferenceException at the start of the game, notification about biome forecast didn't appear. The biome did change after the time has passed. It was 'Feralisk infested jungle' from 'Alpha Biomes' mod. Usually the exception doesn't appear, not sure if it's the specific biome issue or just random glitch.
