Not sure if its just me but am not able to sell anything recently tried chrome and firefox, only tested on unique and set items though.

Roger. Hotfixing now. Should be good in 1-0-22.

Not sure if it's a bug but didn't see it listed under patch notes, am now able to equip all weapons now it seems.

^ I've also noticed that the pieces of armor you can't equip (without penalties) have a yellow text instead of red... Something has changed?

Nothing changed. I changed it to yellow to indicate a penalty or a "impaired" usage of some kind. I changed it a while back so any class could use any weapon. The red gave the impression that you couldn't use it at all.

AAh thanks for the info . Haven't really tried since I saw they were red and thought I couldn't equip.
