Some peeps havent added a custom perk mod & have then realised that quick revive doesnt work in solo mode(by default).
i played around with this a while back & then after helping someone out with it yday i thought id release a "how to".
file link:
https://mega.nz/file/t8wmHTTL#FKNZkujgqrmg4kPfj5KD0tclc86SM0js4A5UFy-VX_wdownload this file & add it to your mod>maps folder. tick in launcher(iwd section etc).
then read the top comments in the file on how to set it up.

credits to bamskater coz the file is basically ripped from his perk mod(whether he's the "originator of that file or not, idk").
Have fun
Phil
