Consistent Data Corruption, crashes and buggy UI. Basically had the game reset itself multiple times today alone. So far duelling people online is about as cumbersome to anyone trying to play as getting spammed by obvious paywall cards makes your duel boring and uneventful until you ultimately lose on turn 2/3. That, or when you find yourself with another person that actually play the game without wanting to OTK, you'll get them down to 1000LP and then they disconnect or surrender...
