I previewed this on 2 weapons which are at 3/4 upgrading and have the same bug, but did not apply the upgrade to make it 4/4;
A 2-hand sword and 2-hand Mace have Basic Skill Damage increase, preview shows an increase in WHITE of +11.7% BUT in brackets the number is RED and says (-11.7%). Which number is correct if I actually go through with upgrading to 4/4, + or - % ?
I did not want to waste material and get pissed off if the number goes negative.
UPDATE: Just checked Pants which are 3/4; at the 4/4 Preview thorns went from 167 to 180 but in brackets says in RED (-57), in this case the math is also wrong it should say +13.
Also, before the upgrades the Affix is weird looking, the star is orange but the writing is grey unlike all others where the writing is orange. Do I really have the Affix?
EDIT: Works OK now, probably beta bugs etc.
