Ok. I think you arent using your entities right.
The Counter-Terrorists will spawn from info_player_start entities.
Terrorists will spawn from Info_player_deathmatch entities.
Make the spawn area nice and neat. Have a grid of entities and seperate them by at least 8-16units on all 6 sides.
Also can I delete the spawn points at any time and replace them in deferent places?
What do you mean by that?
