How are you setting the player's faction to -1?
If it's like this:

Код:

enum ENUM_NAME
{
    pFaction = -1
};

Then it's incorrect. Do it when the player connects.

If not:

Check if it's == to -1 before using fData[pData[playerid][pFaction][fManageRank], or else it'll be fData[-1][fManageRank], and that's invalid.
