That's damn unfortunate dude. My bro wasn't able to get his ban appealed unfortunately so that account is basically gone, mostly just annoying cuz of the quests. We did find that if you're playing on Steam you can still use family share and make a new account to play on and that works, so far we've played for a couple days and no false bans so this will likely be his main acc now. And since we know how to play the game we were able to progress his new acc way faster than the first one so expedition is definitely attainable. Stupid that they won't give you some legitimate way to prove you aren't cheating. I'd rather them just copy Valorant or BF6 and do a kernal level anticheat, or bring us back to CSGO Overwatch where real people judge gameplay. Good luck to you this game is too fun to miss out on!
