I've never actually played the cannon defence minigame before, but I decided to try my hand at it for potential loot. However, I noticed that I wasn't able to get into any game at all. I went through every server one by one, systematically checking Port Royale, Tortuga, and Del Fuego. Even with some of the servers having only 7 other people in there with me, I still couldn't figure out why I was unable to even play the minigame. Is there some matchmaking mechanic I'm not aware of, or is this some sort of bug?
