Packs with multiples of a common

[dickensah]

I (and a few other people I've talked to) have noticed that since AER's release, there's been a bug where occasionally, like once per 2-3 drafts, there will be packs with non-foil multiples. Not sure if it's the actual card data or a display issue (as in, someone merely sees the image for the same common but they're actually different if you were to pick one).
I'm not sure if it's all cards but I've only seen it occur with commons.

There have been 2 bugs that I have known to cause this issue since AER release, one of them is fixed.

1. (fixed 1/26/17) The pack insertion algorithm was incorrectly pulling from the common pool independently (and duplicitously) from the normal pack creation. This created a chance for as many as three of the same common in a pack.
2. (display bug) Currently, if a pack has a foil and non-foil of the same card, both will display as non-foil until the non-foil is picked from the pack. Picking either one will potentially be the foil.
