I was playing on the mobile app, had a Pigment Wrangler on the board (alongside some other creatures), my opponent had 12 life points and I had 6 mana available. I cast Striking Palette and followed with Burst Lightning with the kicker cost. Burst lightning should have been cast for 4 damage and then copied for 4 more damage, but it cast only one. If the bug wasn't there, my opponent should have dropped to 4 life. He had no blockers with fly, was tapped out, and I could have killed him with Pigment Wrangler for 4 damage. The bug made me lose the game in Traditional Draft and I lost the opportunity to get my play in points. The game ended 09h51 Brazilian time (Brasília). I am not sure if the Log worked, because I had to open the game on my computer instead of the app to get the file, since it was not downloading on the cell phone.
