I've noticed some glitches regarding two cards that do not qualify as card bugs per se.
First, regarding Door To Nothingness, when I sacrifice this card, I win, as intended. However, there is no text on the pop-up screen that says I won. Sometimes, (not always)this text disappearance continues in subsequent duels, and the text may also disappear from the buttons on the dialogues that you press to go from phase to phase. The game seems to play properly, except for these graphic glitches, but the only way to correct them is to restart the game.
Second, regarding
Darksteel Forge, the AI wastes disenchants trying to destroy this card, which it cannot do because the Forge makes all Artifacts, including itself, indestructible. This is similar to the problem with
Stuffy Doll. I may need to post this in the bug topic.
I have this game on both my PC (1920 x 1080) and a notebook (1366 x 768) so I don't think resolution has anything to do with the text glitch. Running game with widescreen mod.
