I am using experimental mapgen (mg). I'm not sure if this is an mg issue, caverealms issue, or subterrane issue--I looked at the line in question, which uses biomemap, a local variable which should contain the result of minetest.get_mapgen_object("biomemap"). I don't know enough to know why get_mapgen_object would ever return nil after looking up its meaning. If I restart the server, it works for a while, but when trying to dig deeper in a certain location the server crashes. Apparently the problem happens when a caverealm generates.

Seed: BagEnd
Location: /teleport 17,-566,98 (then start digging down)
MapGen: v7
minetest version: 0.5.0-dev (~2018-02-21)
mapgen mods:

• mg
• subterrane
• caverealms (FaceDeer's fork of caverealms which is integrated with mapgen v7's perlin noise and uses subterrane)
• magma_conduits
• minor mapgen mods: moreores, techic, ... for others see https://github.com/expertmm/EnlivenMinetest/blob/master/etc/game-install-ENLIVEN

Without mg installed, at least one caverealm generates without issues (same seed as above, but new world with no mg):
/teleport -25,-971,121
Since it only happens with mg installed, I moved this issue from FaceDeer/minetest-caverealms#2

See:
https://forum.minetest.net/viewtopic.php?f=18&t=18533

is this the intended behavior? just a question really.

Could you add a readme so one can easily see what the mod does without looking into the code?

Possibly with screenshots.

mg should support the new trees in minetest_game, and also not redefine its own pine tree.
