Describe the bug
When runned on a forge server, the mod won't load, regular trees will genrate instead an you cant place any blocks from the mod.
when you try to load a world created in singleplayer, where the mod does work, the server "ignores" the mod and replaces all of the od related blocks, such as leaves with air blocks.
.
To Reproduce

What if you use the normal, non-deobf version? Also, what happens if you run a server with just this mod? Will it work then? It's a lot more helpful to have that information for the devs to determine the exact issues.

Yes. Do NOT use the deobf version for gameplay. That's for developers only.
