You guys are misinterpreting player IDs.

When a player logs on, they are given an open 'slot' in a list of players.

The ID# is basically the 'slot' number in the list.

Instead of having a huge list that takes up lots of memory, the GServer reuses empty slots (which is why player B get the same ID as player A when player B logs on after player A logs off).

There is no searching involved, it automatically knows which 'slot' to send the PM to, which is also why player B gets the PM you tried to send to player A, but player A logged off.
