1. There are no recipes to make PluginsforForestry barrels from vanilla wood planks. Plenty of them for mod trees (silverwood and greatwood even!) but none for vanilla. 2. Rightclicking a Drum or a Coke Oven with more than one empty barrel in hand will remove the appropriate amount of creosote from the container, but no barrel will be filled. The fluid is simply lost. I spent about fifty buckets of creosote finding this out the hard way. 3. Rightclicking a full barrel onto a drum (even a stack of several) still adds the appropriate amount of fluid to the drum, but the barrel is lost. Since this also happens with creosote bottles, I'm thinking it's not a problem specifically with forestry barrels.
:O 2. FEATURE.* NOT BUG. I WANT. AT LAST, A QUICK AND EASY WAY TO DISPOSE OF CREOSOTE! *Yes I know not really.
