I don't have certain perk machines in my map (ex. Mule Kick) and I don't want them to be given to the player via free perk bottle. How do I take it out of the pool when the power up selects a random perk to give players?

Spiki:

Remove the #using in your mapname gsc and csc

eDeK:

Maybe...

level._custom_perks = Array::remove_index(level._custom_perks, "specialty_armorvest", 1);
