Here's an odd one, this morning I decided to strengthen one of my cards and found that 3 of my cards were unprotected:
- Cat Burglar
- Zeus
- Succubus
The first time that happened to me was with a baby wood dragon, I thought I made a silly mistake not protecting it when I accidentally strengthened a baby water dragon with my baby wood dragon but now I'm no so sure.
This is on Android running the latest release. I'll let you know if it happens again. Currently all my good cards are protected.
