Generating in unwanted areas #21

l noticed that snow mapgen happens in nyanland:

snow uses the heightmap to find the surface (https://github.com/Splizard/minetest-mod-snow/blob/master/src/mapgen_v6.lua#L297), so l assume this happens due to a wrong heightmap, #18 actually shouldn't have happened if heightmap worked right.

Maybe the heightmap is replaced with a dummy if the ground is not part of the generating mapchunk?

Got a similar bug in a server i play, a desert/grass biome got mapgenerated mountains/snow and destroyed half a village present in the area. Some months after (now) it generated again a snow area in the same area. Mapgen v6

The higher stone "hill" was a little mountain-with-snow area strip, now it's kinda an entire valley

volkj, this looks like the map is regenerated at places where it shouldn't
