Firstly, please make sure this behavior is not intended. For instance, if evolving cards do not transform in the 3rd round, make sure the Devotion requirement is met (the ability triggers if your starting deck has no neutral cards).
You can check our forums or even create a post there to check whether the interaction is intended: https://forums.cdprojektred.com
If it is not intended, please contact us and provide the following information:
1. Video showing the issue. Please upload it to YouTube and send us a link.
If you don't have a possibility to record a video, send us detailed reproduction steps.
2. Match timestamp (+timezone) or your opponent's name.
