Hello, I've noticed this once before, but this time I was on the receiving end of it.
When I was at 30/31 components drafted, and only missing 1 flagship, I was passed a bag with 2 flagships in it.
The bot then prompted me to pick both flagships in the bag, putting my total drafted components to 32/31. And later breaking the draft bot, when it could not locate the last component for someone else, due to this.
Once before I've seen it happen with flagships. I don't know if it's unique to flagships, or if it a general issue if you're in that specific situation.
