TileEntity drum cannot be restored, extrautils

Yes, it works.
It is almost always up. The reason there are so many bugs is because we are on 1.6.4, the current version that developers make mods for and as such they are works in progress. When we were on 1.5.2 there were still bugs that the developers wouldn't fix because it was an "old" release.

It's kind of the nature with mods that sometimes there's going to be bugs in some mods. Either you live with the bugs, or don't use the mods. Pretty much all mods we have are usable, or I would remove them.
