I was playing on minecraft ver 1.7.10 and had no problems whis this mod,it was working perfect. Then i update minecraft ver to 1.12.2 and found out that redwood tree is not spawning in the world and can be only found at creative mod,what can be posibly the problem? I have instaled only needed mods like mantle forge and optifine (sorry for my bad england,i'm from russia)
