Plutonium

dude, if we can get survival mods that would be the sickest thing ever lol
plus all of the QoL plutonium gives in general

Is there a way for me to host a custom game but with progression? I don't want to set up a dedicated server if possible so I'm hoping I can make a ranked server fairly easily, I've tried just loading a map (via console) but it just throws a memory error at me for some reason, are there ways of hosting listen servers (or custom games esque servers, if you would) but not have stuff unlocked automatically and having progression/ranked enabled?

@dontknowletsplay I have both this and bonus survival maps 3.0 and would rather just use the console to load these maps, but anytime i try to load one it (seems to) load all 3 and put me in lab with no zombies, and loading 3.0 maps leads to a infinite loading screen. I'm essentially asking:
A. How can I fix it to work properly? (if possible)
B. Can these maps be released individually? (ones that have not already and if it would even solve this issue)
