Issue 1) Missing Excess Cards - If you had enough cards to max out a unit, but had not yet upgraded it to level, then after this update you will only have exactly enough cards to max out that unit (even if you had more than enough before). This is a bug. You should still have extra copies of the card which you could scrap. We’re working on restoring those excess cards (scaled in quantity as mentioned in the release notes).
Issue 2) Missing Cards When Close to an Upgrade – if you had almost enough cards to upgrade before the update, then you may be one card shy now. This is because in some situations a bug rounded down instead of up. We’re working on fixing this.
Possible Issue 3) Missing Cards When Had Enough to Upgrade – a few players have reported having had enough cards to max out Lightbringer, but no longer having enough cards. We’re still investigating whether this is a separate issue or not.
At this time, you do not need to file a support ticket for these issues. We are investigating them and will proactively patch all affected players as soon as possible. We don’t yet have an ETA on this. Sorry for the trouble.
