I'm no expert, but try this:
Log onto east -- you should be at the library on Voltrex
Enter the portal there -- it should boot you
Log back into west -- you should now be in Blackford Castle, and not immediately booted
The problem is probably that the database has you on Voltrex, which is where you should be if you went into the portal
EDIT: Sorry, just noticed this was in the "Fixed Bugs" Forum. My mistake. Opps.
