OK, so I've got a founder with 14+ First Aid because stopping the bleeding onsite gives lots of XP. He can fix a blasted kidney or collapsed lung in about 48 hours (item no longer appears in the health area), and pretty much guarantees that if my people make it back to base intact that they'll make a full recovery.
At least where "full recovery" = all health indicators reading Liberal. Most of my daters can't go on vacation anymore because they aren't uninjured, despite showing no lasting injuries and all health readouts in the Liberal. Does going to Near Death (but having all limbs intact) non-obviously deplete base Health and count as perma-injury? Something else along those lines?
Compare: my Mutant swordmaster Razor Gale has Elite Liberal Health 24. He's been shot from time to time (bringing the Sword to a gunfight, and all that) and made the above-mentioned full recovery, but recently he seems a little buggy.
No matter how many healers I assign, he shows Liberal everywhere but his torso, which stubbornly remains Shot. It doesn't seem to affect him any (no stat depletion, and overall description is Liberal but the docs can't/don't do anything, reset to Laying Low after a day of Tending to Injuries, and I can't send him to the Uni Hospital. If this particular bullet is a permanent addition to his body, it'd help if the game made that clear--this happened once before and cleared up after he got shot in the arm. (Both "Shot" statuses cleared up after putting him in medical for the shot-arm.)
Thanks for your time & consideration.
