Please Fix Max Player Count for Custom Lobbies

So, for the past couple nights, I’ve hosted a Classic SWAT session on Halo 5 PC and they’ve gone pretty well!..
However…there has been many many MANY instances were TOO MANY PEOPLE attempt to join in and my Max Player count doesn’t even work; I’ve been trying to keep the lobby sizes to 10-12 players AT MOST and yet people are still joining in. On top of that, whenever people join AND leave the lobby, the lobby ends up glitching and my game mode/map are reset to Slayer on Stasis every. single. time… As well as the Max Player counter fluctuating up and down depending on who is actually there or not.
There have been many times where people are glitched into the lobby and are not even in the match, but in the main lobby/fireteam, they are there but their emblem is loading. I have to kick them just to fix some of the glitches I’ve mentioned above.

I’m honestly REALLY happy how well these lobbies have been going, it’s just really stressful whenever this stuff happens. Just last night, I had a moment when 22 PEOPLE were in my lobby after a match was over. I had the counter set to 12… I literally could not start the match until lots of people left and/or I had to kick out some. I don’t want to have to resort to kicking people out just because they are filling up slots in my lobby that shouldn’t even be filled.

As a side note, lobby text chat would be really great, it’s annoying trying to talk to the other players only in game and not able to discuss what map to play next or anything else whilst actually in the lobby.
