Broken marked items and repops.

Now I've had the same very very annoying problem twice in a row. I've had a certain item, then I die, it doesn't go away in chromatic flames so it's not overmaxed, while still a ghost I get the item broken marked, so I drop it, sac it, run to the mob who has it, kill it once, since the first time it's illusionary just to find out that it is illusionary again right after. So, the first time I killed it 3-4 times, then I waited an hour, and killed it again. (I know none killed in between.) Still it wasn't there. I log out. 5 hours later I logon in again, go kill the mob (still illusionary) and BAM! It's back. (MIGHT have been a reboot involved as well in those 5 hours, can't remember now.) Today it all happened again, the exact same thing. This time I've waited for 2 hours and still the item is just illusionary! And I know it should be in, none has killed the mob in between, it wasn't overmaxed etc.
