Just saw it. Did three GM nightfalls for platinum yesterday and grinded my way to 1 daily crucible gold today and they are all gone. Bronze and silver are unaffected 5/5 for each. Is there a workaround for this because I greatly dislike crucible grinds and won't be doing another one until this is fixed.
EDIT: Found the issue. Game glitch. When I access Eva for another platinum contender card, the screen goes hazy for a second, gives me a random rare item and loot, and then lets me grab the contender.
Guess that means I don't need to bank with the plate because when I was done, I got the chance to bank the rest of the medals. Specifically silver disappeared at eva and then I banked the 5 bronze.
