Well Vin still gets knocked down in his HP when he logs in after the new update.
I got to thinking about it though and I think I know what is actually happening. I think I had it wrong before which is likely why the fix didn't work.
Ok, for a deep gnome or a forest gnome (those are the only two races that have a negative adjustment to CON) when they log out with full health (for Vin that is currently 48 HP) it saves them as having those 48 HP.
When Vin logs in, he momentarily has a CON that is 2 points higher than usual because the subrace hasn't been applied yet. The system sees he is supposed to have 57 HP, but he is recorded as having 48 HP so it knocks him down to 48. The subrace then applies and his CON is dropped 2 points and it sets his max HP to 48 like normal, but the way that adjustment is made it first notices he is not at full health and so he ends up being 39/48. No more damage is done after the subrace is applied, it just adjusts the numbers from 48/57 to 39/48. The damage is done when it thinks he isn't at full health because he logged in with a higher CON than usual.
I hope that helps.
