Hmm.. actually, I don't see anything wrong.
The problem is the one at OnPlayerSpawn, right?
Try change

pawn Code:

INI_ParseFile(CharacterPath(playerid), "LoadCharacter_data", .bExtra = true, .extra = playerid);

to

pawn Code:

INI_ParseFile(CharacterPath(playerid), "LoadCharacter_%s", .bExtra = true, .extra = playerid);

Also I need more informations.. (sorry)
Write codes for /Characters/%s.ini --> INI_WriteInt, etcetera.
How your /Characters/%s.ini looks like --> Just copy paste what's inside there.

p.s: Before all your write codes for /Characters/%s.ini, try putting:

pawn Code:

INI_SetTag(YOUR_FILE_HERE, "data");
