First off in the lower floors, where there are a lot of death knights patrolling and there's the gay medical officer, I have found two keys that don't seem to unlock anything on that floor. The medical officer has a locked chest but the keys dont work on it.
Secondly, the floor up from that, everyone attacks me, there are guards by their sleeping quarters that attack, also in the soldier's sleeping quarters there's a cleaning imp that attacks. Doesn't the disguise work any more? Also there are locked chests in some of the bedrooms that I can't find keys for - do I have to use lockpicking or are there keys in the level that I just haven't found?
TIA
