I have noticed that a lot of my leaves I have moved have had their name changed to oak leaves even if they are other types I am sure I have not renamed them and they happen to just be the ones I move to other chests with oak leaves please help me~XD (I dont think I have been stupid...)
It was caused a few updates ago, and was recently fixed for any leaves in the future (although it might not have been deployed yet): http://track.empire.us/issue/EMC-145 What you can do to solve the issue is shear all the leaves that have been renamed incorrectly and they'll be fixed.
It was due to mojang screwing around with the data values of leaves. Old leaves have some weird data values, and shop code referenced the old values, but i recently fixed it, but youll see things say Oak when its not really, due to wrong DV. Try sheering as alex mentioned, but im not 100% sure that will work.
