can we add zeds during boss wave?

This mutator is filling my need exactly. Thank you.

Its better if you make a ServerActor=BonusZeds.BonusZedsMut in your engien.ini , but than it does work i think but the server goes saying bla bla MyKFGRI few thousend times a minute :/ Guess you need to update something. Would like to see a Custom boss Mod.
