Hello, I don't know if it only happened to me, but when using this script, in Mob Of The Dead, leaving the afterlife mode the loadout loads but the perks doesn't load (so you lost all the perks), I modified the script, deleting the functions that modify the afterlife system, so that it does not overload the plutonium stock afterlife system.
// Deleted the unnecessary include
#include maps\mp\zombies\_zm_afterlife;
// Deleted this functions
custom_afterlife_save_loadout() // Line 1501
custom_afterlife_save_perks() // Line 1573
custom_afterlife_give_loadout() // Line 1595
// Deleted this two lines from init
// Line 140
level.afterlife_save_loadout = ::custom_afterlife_save_loadout;
// Line 141
level.afterlife_give_loadout = ::custom_afterlife_give_loadout;
I sent a pull request to the project repository so you can review the changes I made to solve this problem.
ps: I appreciate you taking the time to create this script, it's great.
