Has a pretty consistant problem with crashing and a reboot error, it's had that for a while now tho. A new issue I've noticed recently is sometimes cards and card effect either won't trigger, like if you play a card and is supposed to get a counter on it as soon as it's played, it just won't. Another example, start of the duel, have a og blue eyes, try to okay ancient rules, can't play it? No reason for it, just have to set it and wait till the next turn. Great way to get a lose :3
