Today I've experienced a wierd bug that let's me trade/sell in auction some items and doesn't let me with others.

I'm sure these items aren't bounded because I've tried to sell some in auction in past and others I bought from auction so it's defenitely a bug.

Screenshots show how for example with taint staff doesn't appear the add button while with lightbearer's dagger works. The bug obviously is related to also many other items not only tainted staff.

I've done all daily quests and not delivered to be prepared for next expansion and have already some xp ready, can it be related to the bug?
Please help me to solve the problem
