When I grow the trees in BoP, they display off normal, just like the picture shows >.>
Using Forge .1224 and BoP 2.1.0.1004

They display off normal? What? If you're talking about the texture being default, that's an issue with the texture/resource pack, not us

Whenever the trees grow, it will just display one block, and i must right-click on the trees that make them display complete.

What other mods do you have installed? Does it occur with only BoP and Forge?

These...

Try using just BoP and Forge (Probably missed that part in my last post since I edited it in). Looking at that list, I suspect Optifine may be the issue (almost always is), however it's a good measure to test BoP on its own.

The problem still remaining unsolved, this time I only install BoP, and without the texture pack.

Nevermind, misreading, I'll test this myself now

Hrm, this appears to be an issue as of Forge 1219. I'll have to look into what changed and fix it. In the meantime, try using 2.1.0.993 with an earlier version of Forge

OK. Thanks a lot :D

Looks like this was an issue in Forge that has been fixed now: MinecraftForge/MinecraftForge@2af2795

Thanks >.>
