Every server I attempt to join puts me on the "Please wait..." black screen indefinitely on the new update. Could be a bug from the hotfix, but makes the game, once again, 100% unplayable, as I was also victim to the "You are dead" bug... Help!
As suggested by MysteryBox, I tried to log into a server and left it waiting while I went downstairs. Came back up to find myself finally spawned in... albeit unarmed and surrounded by zombies. Seems to be just a bug in the spawn timer display, not an actual game-breaking issue.
