Majesty Hyperion does not properly interact with Sanctuary In The Sky

   Spoiler

   Summon the cards as specified in the situation mentioned above, then attack Majesty Hyperion with Cyber End Dragon.

3. Screenshot OR error code
   I can provide a video.
   The one custom card you see in the video (Creation of Legends) is used to forcefully summon and/or create the cards needed to demonstrate the bug, and has no lingering or continuous effects that could interfere with this interaction.

4. Expected behavior
   The player controlling Cyber End Dragon should take 1300 damage from Majesty Hyperion’s effect, while the player controlling Majesty Hyperion should take 0.

5. What OS are you using
   Windows 10

Update:

Majesty Hyperion MUST be in Defense Mode and receive piercing damage, it functions correctly if Majesty Hyperion is in attack mode…

Update 2:

Performed a test using Elemental HERO Bladedge, powered up with Rush Recklessly and it has the same incorrect result (0 damage to either side)…It seems like the issue is how Piercing Damage interacts with Sanctuary and Majesty Hyperion?

Close this, this was a case of Offline vs Online, it functions properly online.
