Joined in progress message

[JustcallmeHank]

Was playing with a few buddies in the "Player's choice" playlist last night. Started off against bots, Ctl gametype. and as party leader i assume i was host.
During the course of the first game, 4 humans joined the other team. At the start of the next game i got the, 'joined in progress, multiplayer character not available' message, so i guess host switched to the other team.
Problem is i got the same message at the start of every game for the next hour and a half. This has never happened to me before, usually the joined in progress message only occurs when I join mid-game.
Having to play as a character you haven't chosen is not game breaking, but i am confused as to why this happened.
Thanks in advance for your insightful responses.

I believe this happens because of host migration. You were most likely in p2p. If I get that message I'll finish the match I'm on and then back out to try and find a server match.

This happens quite often to my friends and I. It's mostly random and usually NEVER lasts as long as it did for you. I agree with it not being game-breaking but it sure is annoying when it randomly happens for a couple games in a row.

I thought it might have to do with host migration, but every match????? I would happily play on dedicated servers, but ranked matches are almost non- existent in this part of the world. Thanks for your replies.

Try backing all the way out to the title screen so it ends that session. I am definitely not sure, but it seems like to me that the servers gather your connection stats at the first game and it keeps using them. This definitely helps me when I keep getting players from another region.

i was playing a CTL got the joined in progress at the start, lost first round and i was leader second round, we won second round due to me not being an idiot random and between round 2 and 3 i got the message again and that happened again a couple of matches latter
