It might have to do with the fact that you are placing it 0.7 below the ground.

Try placing it at

Код:

CreateObject(1238, X, Y+0.1, Z, 0.0, 0.0, A);

Also, you have a lot of duplicate code you could cut down on.
instead of checking each players:

Код:

if(PlayerInfo[playerid][pCono1] == 0)

Add in a for loop before creating the object which checks for 0, then create the object once an empty slot has been found.
