Healthcare skill will not increase under any circumstance

[BuddySmiles]

Describe the bug

Healthcare is stuck at 0% regardless of anything I do, even skill books are bugged

I noticed it was at 0%, read Big Book of First Aid, and it produces a very large negative number.

Steps To Reproduce

I have no idea, really.

Expected behavior

My healthcare skill would increase :)

Versions and configuration

Additional context

Not sure how to provide my save

What happens if you debug edit your Healthcare skill to 1? Can you increase it by reading / practice after that or is it still bugged up?

I should've mentioned that this was the first thing I did. It has no effect as far as I could tell. I spammed bandages on limbs to see if it'd go up again, as well as reading the book again, same issue.

You can compress your save folder to a zip file and drag it to comment box here.

Looks like it may be related to #47047 ?

I guess so.

_exercise in this save file is already overflowed. I am curious where could cause a overflow.

Fixed file for @BuddySmiles Extract and place in your save file - overwrite old version. There were a few other bugged skills as well.

When was this save created? Was the character created in an older version of the game, or was it created new in the version you were playing?

[BuddySmiles]

I believe it was created on 11412, and its possible I updated the save, I'm not sure if I'm being truly honest. Usually I update saves I've just started because there's never been any issues. This is a first, lol.

Someone else in the thread I posted on Discourse with the same bug mentioned they edited the exercise values and it happened again-- which makes sense, but so far I have not noticed it happening again yet, but I've only checked a couple of times. Maybe if I catch it fast enough I'll know what I did to cause it.

This happens because of an interaction between the focus loss from #47006 and periodic focus-draining effects (such as albinism's sunburn penalty). When focus_pool is < 1000, the mod_focus( -1 ) from sunburn makes focus_pool go negative (mod_focus doesn't check if the end result is >= 0). Then the next practice call takes a sqrt of the negative focus_pool (character.cpp line 2365), resulting in a very large negative number (probably NaN cast to int). This very large negative number is then used to train the skill, causing the observed effects.
