Something isn't working

Not actually fixed. Also, there seems to be another line of rocks at 126 of height. 46/47 is the limit between tundra and tundra_highland in default/mapgen.lua. Those should have been redefined by the mapgen_config mod... The height of the new mountain tops is 80 (126 - 46 = 80)... coincidence? |

Is this the bug you're seeing?
It's much more subtle than I expected... but I do agree it's a problem. |

Yes. That's it. It is subtle and is only visible on escarpments.

Here's my attempt to git bisect: Commits, linked: |

Ok, so git bisect doesn't return the commits in order, but here's the diff that all of those introduce, compared to the main as it was before these https://github.com/minetest-whynot/whynot-game/compare/7519c8d583fdb7169d0e6d70891388c029b2496f..23f29158eefed12b7dc9eb561cd58b397c7a9e66 |

This is a very weird one. I printed all the biome registrations and I don't see anything around 46. The vertical blend is actually 30, and the mountain top layer starts at 80, so those numbers are not adding up. According to the docs https://github.com/minetest/minetest/blob/master/doc/lua_api.md#biome-definition And that seems set properly on the lower biome. I tried to change the vertical_blend to 10, and that didn't affect the height of the rock line. https://github.com/minetest/minetest_game/blob/master/mods/default/mapgen.lua#L977 |

It's not the ore stratum... changed them to no avail. Tried tweaking other settings without luck. |

I can reproduce this with MTG! Though it's not as obvious possibly because of the thinner filler (ex. dirt) layer.

Even in MTG's biomes heavily modified with ethereal NG

At this point it's all I see :( There does seem to be something weird happening at block 46. |
