[HPC] PLEASE HELP!! *URGENT

[Sgt.Peppers]

Hi everyone, I've been trying to swap the ambiance sound tag in blood gulch for one in another map, I go to blood gulch, it plays fine, then it plays the regular ambiance (the blood gulch one) for about a second and immediately goes back to the one I swapped it with, making it sound really bad.

Can someone PLEASE help me?
