I did 4 Raven keys today.... no issues.
I'm on Android, so it sounds like an iOS issue.
I had probs day before yesterday, decided to check Google play app store for possible update.... sure enough there was. Never saw any info about it, here or FB. And we just had an update just days before. So anything is possible.
When there are issues and bugs, it sux.
But when stuff works right, this is a pretty cool dungeon.
Kind of ironic though....
You have $, but game is broke.
My game works, but I am broke.
Good luck.... btw, enjoy your new Dark Lilith.😁
