After the recent change of the home-world hopping option, I noticed that neither commands for /blist add and /blacklist add work anymore.

I've tried the original version:
/blist add forename surename
/blacklist add "forename surename"
/blist add forenamesurename
/blacklist add "forenamesurename"
/blist add Forename surename@world
/blist add "Forename surename@world"

Neither of these options allow to blacklist someone. Only through the contact list, which is... puzzling. Even the ingame support instructions (when searching for it on helpdesk support) says to do as advised, and it doesn't work anyways. I ran some tests with PC's in town in limsa (because it's a huge test site), and nothing seems to prompt it.

Does anyone know the new command to make it work?
