Today I have chop two exactly equal trees, planted the same day (10 real days ago on her native soil) and of the same type. Both were q15. Both had grown to the top.
Tree 1 has given me 1 log q15, and 4 blocks q10 from remove the stump.
Tree 2 has given me 4 blocks q15 when I was chop it (on the inventory), zero log and 4 blocks q10 from remove the stump.
It's that normal or is a bug? Why the difference?
