HUGE Bug - Attuneable items don't work

[Theeper]

I don't think attuneable items work at all. They will attune, but once you zone, it's not attuned anymore. It doesn't appear to set the "instnodrop" field in the inventory table when you attune the item. Even manually setting the field doesn't seem to do anything .. unless it's supposed to be some odd value that I didn't try.

I can't find anything about attuneable items in the opcodes, so either it's called something else, or it's not there at all.
