when I click play on steam it just goes running.... and then stops, without launching anything

hey guys, i just finished progressing to sequence 3 and your forced to look at Kenways Fleet but it forever loads softlocking the game since it is essential to progress the story. Has anyone else encountered this issue??

Hey guys im trying to 100% black flag and im left with the multiplayer achievements anyone want to help me get them together is welcomed

I SEE THERE'S 800 PLAYERS ON. SO DO THAT MEAN THEY ARE ON CAMPAIGN OR MULTIPLAYER? AN IF PEOPLE ARE PLAYING MULTIPLAYER IS IT SAFE OR AT LEAST SAFER THAN COD GAME SERVERS

Me and a friend started playing this games multiplayer mode on brand new accounts. Just bought it. We queued into wolpack to find eachother, and then added eachother as friends while in the lobby. Afterwards, even though I'm given the option to send them a group invite, they don't recieve any at all. Their invite button on the friends tab is greyed out entirely. This wouldn't be an issue if I could publicly host higher difficulty wolfpack lobbies, but those force you to create sessions on private for so...
