I have following problem: there is no other biomes for Earth than grasslands it seems. Sometimes for 0.1 sek. north pole biome flashes in random places... I think that i have up to date textures for RSS. Any ideas? Maybe i should use custom biomes to fix this? EDIT: Strange. When biomes are visible in map everything seems to be fine. Same thing in Custom Biomes. But Kerbal Engineer shows that there is only grasslands and when im trying to make science it is always "above grasslands". Why?
