Strange! My server was relocated today and when I set it all up through GameTracker I noticed that instead of my 64, GameTracker shows the server as being 32 max. I decided to wait it out a bit to see if it would change but it is still stuck at 32 rather than 64...

As you've read, we are awaiting a fix from EA/DICE.

How does this happen with some servers but not others? Is it some totally random factor? Because it was working properly with my other server until it moved (with the same exact settings).

From my understanding it is in the maplist setting

ConquestLarge - Conquest 64 Up to 64
ConquestSmall - Conquest Up to 32
RushLarge - Rush Up to 32
SquadRush - Squad Rush Up to 8
SquadDeathMatch - Squad Deathmatch Up to 16
TeamDeathMatch - Team Deathmatch Up to 32

Weird! I just realized that in Procon, it shows my server at 32/64. I didn't see that last night once I had my server relocated. I even have all the maps set at ConquestLarge0 so I'm not sure what's up...
