Sleeper's Tomb Error
 

I've been trying to enter the Sleeper's Tomb on 2 different non-legit servers and both give me the same error when I try to enter:

"You are not yet experienced enough to pass through an inter-planar portal."

I've completed the quest to get the key and my character is level 75, but I still can't enter. I've tried the #zone command as well as clicking on the portal in the Eastern Wastelands directly. Am I doing something wrong, or is there a problem with the 2 servers I tried this on?

I'm not 100% positive if this is the correct forum section, so I apologize if it's not.

The servers where you tried to enter Sleeper's Tomb could have a higher level restriction placed on the zone, it could be locked out completely or it could have an custom entry quest. You might get a better answer by asking a gm or admin of one of the servers that you play on about why the zone is restricted.

I sent them both messages, hopefully they'll reply eventually since I've never even seen the Sleeper's Tomb before.
