This may have been due to the server load last night, however the mission "Kitting Up" requires two objectives. Obj 1 is to obtain a rifle from a crate and Obj 2 is to speak with an NPC about kit's.
Obj 1: Error occured with obtaining rifle from crate. Near as I could figure there was 20 players in the instance. Once the crate flashed, and the item menu showed the rifle, was unable to click "Take" or "Take All".
I moved around to multiple instances, and once I located on with less then 20 players, issue appeared to be resolved.
I too, encountered this last night. Did you file a bug report already? If not, please file one or do a quick search and add yourself to an existing ticket. This'll help the devs.

You probably had 4 or 5 folks sitting around the crates spamming the f button.
