Some nodes seems "unloaded" and only thing that fixes them is using /deleteblocks to recreate them, a video here:

>>> Is the bug reproducible?
I don't really know but try creating a new minetest game, define 1 node and put this code(the one I'm using):
Code: Select all
1 minetest.clear_registered_biomes()
2 minetest.clear_registered_decorations()
1
2 minetest.register_biome({
3 name = "basic",
4 node_dust = "basic:dirt",
5 node_top = "basic:dirt",
6 depth_top = 1,
7 node_filler = "basic:dirt",
8 depth_filler = 3,
9 node_stone = "basic:dirt",
10 y_min = 1,
11 y_max = 31000,
12 heat_point = 0,
13 humidity_point = 50,
14 })
>>> What is your version of Minetest?
Minetest 0.4.16 installed from apt in Ubuntu 18.04
Also debug.txt does not help, all it says is about missing textures such as heart, player_front and back and crack anylength
>>> Extra:
The blocks start turning into "air"(I don't really know) only at -46 y coordinate
