Issue description

Branches for custom trees in custom biomes keep dropping on the ground. Is there something I'm doing wrong? All im doing is selecting the leaf block I made and selecting it for branches.

Make sure you tag your log blocks in logs tag group. Also keep in mind only one tag group with same name can exist so tag all logs in same tag mod element minecraft:logs

I just created a tag but I do not know how to make it a log tag, could you explain it to me?
