IMPORTANT
INSTRUCTIONS TO FOLLOW IF YOU UNINSTALL MID GAME AND FIND THAT YOUR HEALTH REGEN IS NOT WORKING
Open the console and type - "player.getav healrate" there should be return message saying that healrate is 0.01 - If so, then type into the console "player.modav healrate 0.69". This will return your Health regeneration to normal.
If, for some reason, your healrate is not at 0.01 then just adjust the value you enter so that it resets Healrate to Vanilla default value (0.7).
This applies to all Actor Values and will work for Stamina and Magicka as well. So the same rules apply if you have any trouble.
Default Values:-
Healrate = 0.7
Staminarate = 5
Magickarate = 3

So, I got an issue about my natural passive health regeneration won't work at all, probably because of a mod that I'm not aware causing this. Then I found this post but the HealRate value is at its default which is 0.70.
I almost gave up because I tried to deactivate 10+ mods I recently installed and none of them solved my problem. Until I found a reddit post that discussing about disabling the passive health regeneration, and I found that there's no point modifying HealRate value if the HealRateMult is below 0. Read https://en.uesp.net/wiki/Skyrim:Health for more technical explanations.
So here's how I identified the problem, I typed: player.getav healratemult and turned out the value is -24. So that's the probem, I just have to set its value to the default which is 100 by typing: player.modav healratemult 100.
Hope that helps :)
