Hey kyrllon,
The board not appearing for player 2 is a known engine issue when entering a match (through the menu) from in-editor play sessions. Starting the match with the arena already loaded in the editor OR running the game through standalone clients should not see this issue.
This should be the same result for both 4.21 and 4.22. If there is a specific repro on 4.22, let me know through the support email and I can take a closer look.
Hope this helps!
Hey Nyfaria,
Creature cards should always go to the graveyard when they reach ‘0’ health, if they receive damage.
Does the card start with 0 health? I would be interested to see the other card settings being used to see if I can reproduce this on my end.
