If you get a blank menu with an up arrow, click the up arrow. It should bring you back to options. I do not know if we have had any reports on the robe issue. As for the robes, if you cannot buy the robe (from Kora at the Hermit Camp) then you can get into the Morroi Camp via an alternate route (you will have to get past a gelatinous cube).
If you can post a save game with these issues, I can replicate them and work on resolving them.
