J'ai retrouvé :
-> Repeated Blood Gracht & Salamun Market matches :
"We’ve already identified the cause of this problem, it is related to the ‘ANY” map selection preference, and we should be able to get a fix out soon in one of upcoming patches. In the meantime if you get trapped repeatedly playing either Blood Gracht or Salamun Market, you can quit your game, then within Find Match > Map Selection, choose a non DLC map. The game will place you into the map you have selected when you attempt to join a game, and once your match is finished, map voting will happen as normal and you can vote on whatever map you wish. We understand this isn’t an ideal solution and will try and get this resolved a.s.a.p."
J'ai pas le problème mais apparement, il faut filter la map avant de lancer la partie puis à la fin de celle-ci, le vote normal devrait reprendre. A voir si ça marche ...
