Another graphical bug

Sorry i don’t know the card, but I was playing a game tonight and there is a card that makes chains on the screen in a criss-cross pattern, like 3 rows of it… I was afk when they played whatever card, but that effect never left the screen for the rest of the game. I would say another 12-15 turns… it just stayed there even when the board was cleared. I’ve been playing this game since like season 1-2? and I’ve never seen this. Two graphical bugs in a row in less than two weeks, and yes my video card drivers are up to date, Windows 10
