Trees dont spawn when loading a new world. This started when i updated all my mods on curseforge. So the trees before i updated are still there. Its just new ones are not spawning when loading chunks or loading a new world.
Heres smth i found on logs that i think might be causing the problem.

Error whilst loading type "SoilProperties" with name "dynamictrees:rooted_moss": [primitive_soil] Could not find block for registry name 'minecraft:rooted_moss'.

After that theres just stuff like

Exception loading blockstate definition: dynamictrees:blockstates/rooty_rooted_moss.json: java.io.FileNotFoundException: dynamictrees:blockstates/rooty_rooted_moss.json

And goes on with every block that has the name "root" in it.

Stale issue message

Both of those issues should be fixed as of the latest update but would not have been related. Do you have any other mods installed that mess with worldgen?

This issue has gone stale due to it having no activity for 90 days. Is this still a problem?

i have been having the same issue, namely spruce and dark oak trees

I am also having this issue, but it's sporadic. It's difficult to replicate - sometimes the forests generate perfectly normal, and then once this "begins," very few trees generate again. Forests or Savannas for example are all completely empty. I was able to replicate this with just Biomes O plenty, Dynamic Trees and Terrablender.

Edited to Add, I do have Dynamic Trees for BOP as well.

Same issue here, I am going to investigate this further on my end as far as I can. I have a minecraft world where old trees exist, but all newly generated chunks are void of trees. A new map that i created for debugging... well doesn't generate them.
Affected are: Birch trees, Dark Oak trees, possibly even more.
I also updated my game so I will edit this once I tested it again on whether the issue still persists.

EDIT: The normal overworld is fine now, there's an issue with Chunk by Chunk spawned chunks though, maybe it's a problem on their side though.

similar issue here. spruce and dark oak do not generate naturally for me in the biomes that they are supposed to
