[TBC] Arena Crash Server

[aspirexenux]

On the TBC server, when I launch a ranked 2v2 game, the server crashes. I've tried many possibilities (launching the server with fewer players, launching the server in BETA to get the new updates, waiting 15/20 minutes to allow the server to start properly) but without success. :(

I remain available if you have any solutions to offer me, thanking you in advance. :D

To add to this in an attempt to help the fix:
TBC arena crashes during 2v2 arena port/join handling. It happens after the queue forms and the arena prompt appears/ports begin. Crash is in WorldSession::HandleBattlefieldPortOpcode, BattleGroundHandler.cpp line 492, called from BattleGroundQueue::Update, BattleGroundQueue.cpp line 1372. Tested both skirmish and rated. Skirmish seems to be bugged and appears to be incorrectly logged as Plr Rated:1, which could explain crashes with skirmishes, but rated 2v2 with a valid arena team also crashes. Crash dump variables include isRated=1, arenaType=2, bgTypeId=6, bgBracketId=6, mapId=0x22F, isInvitedToBgInstanceGuid=2.
Extra detail: I have managed to join two 2v2s so far, in both only one member of the opposite team got ported to the arena.
In mine, we both got ported (me and my bot) once, and the other time only I got ported.
Could this maybe be related to how the porting of characters is being handled?
