Nice work on all the recent compat stuff and bug fixes. I had some time to test stuff in the new version today, and I just wanted to confirm that pretty much all the bugs I've reported have been fixed, including the thing with the Ender Garbage Bin (I can run my Coke Oven uninterrupted again!). One thing I noticed though. The vanilla Flint item lists the tool stats now in the tooltip, but it's still missing "Possible Tool Enchantments".
I don't think this is a bug, but it might be an oversight: GT Hoppers remember their configured stack-size when harvested, but not whether or not they were set to "exact" or "divisible" mode.
For this next thing, I'm not sure if there's anything that can be done to fix it, but I figured I'd report it anyway. iChun's Gravity Gun and Portal Gun mods let you pick up blocks and place them down elsewhere (Gravity Gun uses right-click, Portal Gun uses a hotkey, "g" by default, I think.) Doing this with a GregTech ore causes the ore to become visually bugged (it becomes an Empty/Unknown Ore), but doesn't seem to affect the ore you get from harvesting it.
