After installing this patch i have noticed that in both Auction House and Arsenal any additional helmet or armour features are double-displayed, was it intended?
ps: some items have different features in different places, for instance - the vitasuit deluxe during the game is health +6, but in haven it's health +7.
Health bonuses get debuffed depending on what tier you're in. You'll only see the full health benefit from your 4* armor/shield/whatever in T3. http://wiki.spiralknights.com/Tier#Equipment_Reduction
I haven't seen the duplicated display bug yet, though, because they also managed to break steam logins with today's update. :P
