[tuliorcc]

When picking the last card in a draft, the game freezes and crashes. Happens more often in FIN drafts.

This issue has not been updated in a while and has now been marked as stale. Stale messages will be auto closed.

Reportedly still happening. Might be addressed by #7519; will check soon.

The issue appears to be that on rare occasions, Final Fantasy boosters generate with two copies of whatever is in slot 8, causing them to have 15 cards instead of 14.

(Note how player 7's pack has 15 cards, not 14)

I don't know enough about the Booster Generator system to say why the booster configuration leads to this, but the current draft editor gets very confused if not all players have the same number of cards in a pack.

The deck editor update will prevent it from crashing, but the underlying issue of packs being generated incorrectly will need to be resolved separately.

Should be resolved by #8313.
