I think I found a bug. I had 145 HP, then I upgrade HP a few times in Skills and it dropped down to 120hp xDYe, when you upgrade your HP in the skills, it resets/removes all of the HP you gained from armour.
Well.. What if we just call it a feature? xD
Thanks for letting me know, I'll look into it, probably just my very bad math skills calculating things wrong!
Putting the armor back on might have fixed it, but still, bad feature :p
