Hello there...
After a search of the forums, I have not seen any other reported instances of this. For me, for some odd reason, I can not see, target, or interact in any way with Mummys and Flesh Golems. I will take damage if hit, will be cursed, whatever, but I can not see them. I don't even know if I swing wildly if I even hit them with glancing blows.
I also seem to have an issue with the Subterranean and the Devil Battle Ground in Shavarath. I crash every time I attempt to enter those zones. I just get the response that DDO is no longer responding. I can hear team members for awhile, but they can not hear me. They say they can see my dot on the map, but I never get there.
If I try to log back in right away with the same character, after I select the character the game will crash as I assume it attempts to log me into the zone. If I log in another character or wait for awhile, I will log into the Marketplace or whatever, but not in the zone in question.
