The Lost Cities

2.0.26-alpha:
- Fixed a problem with cities generating under very high biomes. Sometimes pieces of the original landscape were still present
- Potentially fixed an issue correcting block states in a not-fully-generated chunk
- Fixed the check if a biome is an ocean or not
- Fixed the detection of biomes in general
- Lower the stone border a few blocks so it is always covered by terrain (there were sometimes gaps with ocean chunks adjacent to street chunks)
- Clear land above above-ground railway stations
