Thousands of Order of the Ancients Medallions

I've completed the Order quest and delivered all of the medallions.

About a couple of hours later while I was finishing off some side stuff in England, I decided to exit the animus to check for new notes on the laptop.

I then re-entered the animus and noticed that Eivor's inventory was marked as if there was a new item added (I usually always check for new items so that I always know when something new has been added).

I go down through the items in my bag and notice that 8,608 copies of Order of the Ancients Medallion have been added to my inventory.

This is obviously some sort of bug. But I guess it's not game-breaking at this point.
