Relic Selection / Upgrading During Intermission makes game unplayable

[Krueller]

Just happened. Had a good group of people on a survival mission. Was upgrading and equipping a relic for the second part of the survival run.

If you select to upgrade a relic while the countdown timer starts, and you equip it just as the mission starts you get the message "Equipping" and you're unable to do anything. Not move, attack, chat etc.

Same just happened to me, only I had the "Please wait" idle text the whole time. 
Couldn't escape, type, move, etc. 
The only way I got out without losing my loot was to (via Discord voice chat) have the rest of the team leave me for dead, bleed out, and then extract which pulled me as well.
