Cards not appearing in Collection

I opened 24 packs using the pack simulator and when i went to check my collection only 25 cards were added.

I tried clearing my cache and nothing happened.

Any help?

Issue is also occurring for me.

I tried exporing the pack simulator pulls into a ydk to import into the collection

and that still failed as well

*Edit what I found seemed to be incorrect information

Could it be multiple copies that go missing?

Having the same issue. The log shows a card being added but it doesn't appear in the collection nor does the collection number go up.
