I am new in this forums. I have completed gta sa 2-3 times and now when i started playing again i got stuck in san fierro. After the mission Da Thang Nang Boys (or something like that) there should be a phone call for another mission location but i am not getting it. The map simply doesnt show any mission location. I have modded the game and am currently using a trainer (After i completed the game). I have finished the driving school and zero's missions also. But I did use the trainer once in the driving school and also used the cheat "ripazha". Is this problem occuring because i have modified the game or is this because of the trainer?
