Hi guys
I already post this topic in main page but i think here is better....
so....
HERE I have a really big problem
Ok let me explain....
I downloaded a map from C&C labs for generals zero hour
and I used it in shock wave .....
I decided to add something to it with SW world builder....
and the number of objects reached 2500
after that I entered game to play this map ...and then after some constructions none of my tanks -soldiers and whatever on the ground didn't move!!!!!!!
there is none of lags......but i dont know why this happend....
but a strange think is that whatever in the air like jets and helips could move!!!!!!!!
plz help me solve this problem
