Don't worry -> cheat your way through!
taken from Kevin Dorner's baldurdash fix:
If you are experiencing the bug of being stuck in a hostile, sealed Ust Natha, type the following exactly into the console:
CLUAConsole:CreateCreature("UDARDUL")
then press Enter, and kill Matron Mother Ardulace. Don't forget to pick up her goodies. :^) Verify you can leave Ust Natha by placing the cursor over the exit and looking for it to change into an exit cursor, or leaving...your choice. Make sure you have Adalon's eggs if you were questing for them before leaving.
If you are experiencing the Beholder quest bug, type the following exactly into the console:
CLUAConsole:SetGlobal("PHAERESPEAKBEHOLD","GLOBAL",0)
then press Enter, and then talk to Phaere, and kill the Beholder that appears.
Hope this helps
