This Hideout no longer allows trading

My hideout won't let me put things in my Faustus shop anymore, and gives me the error "This hideout no longer allows trading, Please re-enter the Hideout to create a new instance."

I've tried everything to "create a new hideout instance", but nothing is working. I waited 30 minutes in a different map to reset the instance, I've logged off for more than 30 minutes, I've swapped hideouts with Helena, but nothing works.

Could you please look into this? It would probably make me quit the league if I'm completely barred from using my Faustus shop...

Thank you in advance!
