I noticed my stats are a bit off (not by much at least, and I know they always have been) but I'm wondering if part of this is because the eternal belt buckle that you can add to belts does not show up?
I looked about 7 pages back in the bug report and didn't see a topic for it so I'm mentioning it.
At the same time I'll admit that I haven't done the math to see if that is really the issue, but either way it is odd that the extra gem slot doesn't show.
The tooltips not showing the extra gem is actually a coding difficulty on our end and we're still working on it, but I can assure you the stats are still calculated.
The HP and Stamina difference is really a minor rounding off thing - you can see that the only difference is 10 HP, which is caused by the 1 Stam difference. Other stats are dead on correct.
