Raril Giral in the Black Shalk Club (Vivec Foreigners area) will rent me a room - but it doesn't get unlocked automatically, and picking the lock just shows the bed as un-sleepable because it's still flagged as being owned (minor problem).

With regards to huleeya can you please type in console "sqv fbmwMQ04c" when he's near jobasha and post a screenshot of it ? It will help me debug
