  1. Bug description
    [Describe what the bug is in your own words.]
    Having an odd issue with playmats loading.
    I matched all my playmats to my decks by naming them accordingly, and they’re all *.jpgs.
    What happens is I load into a game the first time, and the playmat loads correctly. However, the playmats are incorrect in every subsequent instance. It’s sort of like the game starts to default to a playmat for every other deck, until I restart my client.
  2. Bug reproduction steps
  3. Have 12+ decks, each with custom mats in the dedicated “playmats” folder.
    Enter any game once. After the game concludes, after exiting (not rematching,) enter another game.
