Which items are you guys having problems with? I encountered
something similiar with Antonian Javelins yesterday (didn't see this post), but they're not lore.
I've been able to swap other items without issue (although I haven't tried them all yet). I did run into a lore item issue: I tried to loot an item off my corpse when I already had one banked from before I beta buffed, but that's not really a bug.
