Forge v14.23.2815-1.12.2
Redwoods v1.0.0

I got this crash almost as soon as I launched the game.
Here's the crash report.

Also, could Dynamic Trees ever be supported?

Nevermind, just saw the hotfix.

Yeah, sorry about that. I thought I tested everything!

Also, I don't think that my trees would work well with Dynamic Trees since they're completely different from the types of trees that Dynamic Trees is meant to support. I imagine that something like https://minecraft.curseforge.com/projects/dynamic-trees-traverse-compat would be needed, but I don't think that it would be able to retain the look of Redwoods conifer trees.

Ok, that makes sense, and thanks.
