Look closely at this snippet from your code

PHP Code:

     cache_get_field_content(i, "SpawnX", tmp);    FactionInfo[id][fSpawnX] = strval(tmp);
     cache_get_field_content(i, "SpawnY", tmp);    FactionInfo[id][fSpawnY] = strval(tmp);
     cache_get_field_content(i, "SpawnZ", tmp);    FactionInfo[id][fSpawnZ] = strval(tmp);
     cache_get_field_content(i, "ExitX", tmp);        FactionInfo[id][fExitX] = strval(tmp);
     cache_get_field_content(i, "ExitY", tmp);        FactionInfo[id][fExitY] = strval(tmp);
     cache_get_field_content(i, "ExitZ", tmp);        FactionInfo[id][fExitZ] = strval(tmp); 


you are using strval function which converts strings to integers,
this is how strval works

PHP Code:

     new floatNumber[7] = "15.623";
     printf("%f", strval(floatNumber)); 


This would print 15 not 15.623, because it's converted to an integer (the float part is removed)
more exemples

Code:

     strval("6.23")           ==> 6
     strval("96494.544")   ==> 96494
     strval("1.0")             ==> 1

following this logic, when your current position has been calculated GetPlayerPos(...), let's say the positions are

Code:

X = 1663.2345
Y = -4959.2783
Z = 3.296

when you sue strval function on them they will be integers meaning

Code:

strval(X) = 1663
strval(Y) = -4959
strval(Z) = 3

see? All the float part is removed, and when dealing with positions, the float part matters, that's why the pickup isn't created in your exact position but offset a little bit

the correct way to go around this, is to use floatstr function instead of strval, which converts strings to
floats

*A correct snippet

PHP Code:

     cache_get_field_content(i, "SpawnX", tmp);    FactionInfo[id][fSpawnX] = floatstr(tmp);
     cache_get_field_content(i, "SpawnY", tmp);    FactionInfo[id][fSpawnY] = floatstr(tmp);
     cache_get_field_content(i, "SpawnZ", tmp);    FactionInfo[id][fSpawnZ] = floatstr(tmp);
     cache_get_field_content(i, "ExitX", tmp);        FactionInfo[id][fExitX] = floatstr(tmp);
     cache_get_field_content(i, "ExitY", tmp);        FactionInfo[id][fExitY] = floatstr(tmp);
     cache_get_field_content(i, "ExitZ", tmp);        FactionInfo[id][fExitZ] = floatstr(tmp);
