Currently regulates the usage of CMSG_CHAR_ENUM only, but can be easily
extended to detect inappropriate network behaviour by using
AntiDOS.AllowOpcode in WorldSession's handlers.
These were non-wdb fields that didn't have much use.
Most quests that were using these fields (not many) should still work,
however, if you find any quest that worked before and is now broken
please report it in the issue tracker and it will be promptly fixed.
Mind Vision has Aura Effect SPELL_AURA_BIND_SIGHT which adds the target to a special Map container i_objectsToSwitch, used to switch grid containers for target Creatures of this Aura Effect.
When the target is a Creature, when the Creature is removed from world it's added to i_objectsToSwitch and then to i_objectsToRemove, iterated in this order in Map::RemoveAllObjectsInRemoveList() so the reference in i_objectsToSwitch is valid.
When the target is a Player, when the Player logs out it's added to i_objectsToSwitch but then Map::RemovePlayerFromMap() deletes the Player, leaving an invalid reference in i_objectsToSwitch.
Since the whole point of i_objectsToSwitch is to store Creatures and since the stored references are used only if the condition "GetTypeId() == TYPEID_UNIT" is verified, it's safe to add only objects of TYPEID_UNIT type to the container.
