Can't pick item while running mission...

... is it a new feature? or a bug...
i need to run mission time to time to get new stuff (nano or other). Usually i run and pray ;), but i find the item often, then i got the reward .
I know that atm, mission are buggy on reward, but now, i cant at all pick the item too (for retrieve mission) when i m aggroed.

That s mean that mission blitz are allowed only for conceal classes???
As a doc, i'm always broken, and now, i cant run mission anymore to get quick stuff.
