Try changing

Code:

SetPlayerHealth(playerid,99999);

to

Code:

SetPlayerHealth(playerid,64000);

Although I'm pretty sure its not the case, the integer you specify might be overflowing and changing into a negative number because its too high. However, since you claim its not any of the filterscripts and its the only part of the spawn code that changes the player's health, I suggest you try changing it.
