Just a warning to all the high AC types out there.
I aquired my Dragon touched Robes which have a AC of 6 and +5 Protection bonus, when I tried to bump it up by placing an alchemical Dodge bonus on it I was rewarded with the protective +5 quality being made inactive, there by ruining my armor.
Of course, +Oldac+, the in-game rep on Argo would not help by replacing the armor because of this bug. Don't know why I tried, I have never been successful getting them to do much of anything except once respawning Delera when she bugged out.
I posted the bug report and we'll see what happens, I won't hold my breath.
Just a warning to those who have the same intentions.
