Рандомно крашит (т.е. может крашить, а может и не крашить) сразу после захода игроков на арену

[Amaru]

Кто-нибудь знает, от чего такое может быть?
Рандомно крашит (т.е. может крашить, а может и не крашить) сразу после захода игроков на арену.
Имеется код:

bool BattleGroundDS::SetupBattleGround()
{
    if (!AddObject(BG_DS_WATERFALL_VISUAL, BG_DS_WATERFALL_VISUAL_ENTRY, 1291.56f, 790.837f, 7.1f, 0.0f, 0.0f, 0.0f, 0.694215f, -0.719768f, RESPAWN_ONE_DAY))
    {
        ERROR_LOG("Dalaran Sewers: Can't Spawn GameObject %u!", BG_DS_WATERFALL_VISUAL_ENTRY);
        return false;
    }

    if (!AddObject(BG_DS_WATERFALL_COLLISION, BG_DS_WATERFALL_COLLISION_ENTRY, 1291.56f, 790.837f, 7.1f, 0.0f, 0.0f, 0.0f, 0.694215f, -0.719768f, RESPAWN_ONE_DAY))
    {
        ERROR_LOG("Dalaran Sewers: Can't Spawn GameObject %u!", BG_DS_WATERFALL_COLLISION_ENTRY);
        return false;
    }

    SpawnBGObject(BG_DS_WATERFALL_VISUAL, RESPAWN_IMMEDIATELY);

    DoorOpen(BG_DS_WATERFALL_VISUAL);

    return true;
}

Если объекты не добавлять, крашить не будет

Из кастом патчей стоят mtmaps

В vmap code, может быть что-то не то с координатами.
