Please explain your issue is in as much detail as possible.
When I want to join assassin, first society available in the list, I can't join it by clicking on the button. When I click and I move the pointer on the next society on the list (Hel confrery (not sure, I do play in french)), then it is like I asked to join this second one.
It is quite annoying, and before my update to Holy Fury and Jade Dragon this week, all worked perfectly fine.
