EDIT 2024-03-12, 09:36 UTC:

The currently running Hero League has been canceled. We are investigating what caused the issue and hope to run the event again soon with the same configuration.

Hero League will include the same Featured Families as this iteration when it runs again.

We have replenished energies for players and we apologize for the inconvenience.

We are aware of an issue affecting Hero League battles.

We are currently investigating this and will update this announcement when we have more information.
