When placing a boss monster, the monster’s main sprite doesn’t appear. The only thing showing are the visual effects and a pink set of shapes that probably are the sprite’s shapes.
I assume the game failed loading the textures. Linux is case sensitive, so if the code wants, as an example, Dark_Magician.png, but the file’s name is Dark_magician.png, the game will not find the file. The other visual elements and card sprites are working as intended from what I can see, so it’s probably something only related to the invocation of boss monsters?

The only added files to the base game are sleeves and playmat .jpg files. The video above was filmed while spectating an online lobby.
