Re: [Mod] Conifers [0.3] [conifers]
You have to go above 30 m if you didn't edit the mod. You might wait a little bit too.
Otherwise, if you want to speed up the tree generation, change the the line 31 of conifers/init.lua as this:
local INTERVAL = 3600
local INTERVAL = 600
It will generate a tree each 10 minutes instead of each hour (proportionally to the game's time).
