Under my eyes, it seems like the generic bug of not checking if the player is online, or not.
Try to place ontop this:

pawn Код:

if(!IsPlayerConnected(playerid)) return 0;

This should work most of the time, I encourted this too.
You can understand it by your own:

Код:

[16:54:37] [debug] #0 0017ff04 in PlayerUpdateListener (playerid=44)
-- Okay! So it crashed on PlayerUpdateListener, under playerid 44. But wait? Do we even have an id 44 connected? (After checking again)
- No! Script is getting runned over and over when the player isn't even online! It tries to run a native that requires a player to be online for.
- Yes? Seems like we have a bug of a null string attempting to change the active MPPool of the server, resulting in a nusty crash.
