First of all, please consider whether your problem actually
is a bug.
Individual problems with your account or problems connecting belong in
troubleshooting while ai suggestions (this includes ai "fails") belong
here. Spelling or Grammar suggestions also belong in the
Game Suggestions and feedback board. Problems with the forums do not belong here, either. This place is for in game bugs.
Before reporting a bug, please check the
not-a-bug List, as well as the
change summary for the latest version (the "bug" you're reporting may be an intended card change). Confirmed bugs will be moved to the
confirmed bugs section. There are also certain general types of bugs that are known and do not need to be individually reported, these include:
Spoiler for known, general bugs:
Desynchronization
Symptoms: Your opponent's deck, cards, health, and quanta keep changing rapidly. Both players disagree about what happened. Very general bug that happens only in pvp, in some cases when a specific card combo consistently causes desynchs there is a reason to post this. These cases can usually be observed by having different outcomes when you do it, or the ai does it.
Rapid Draw problems
Symptoms: Not drawing a card you should have, despite having room for it in hand. Being forced to discard an invisible 99 cost card.
Rapid Click Problems
Symptoms: Playing cards for free, playing an infinite number of cards, discarding more than one card, and various other illegal game moves.
Do not ever, ever, ever post names of suspected cheaters or hackers in chat or on the forums. Almost every case of hacking/cheating during a match is, in fact, a symptom of desynchronization. Forum staff can do nothing about hackers or cheaters, so please, do not post about players accused of cheating.
Finally, when posting bugs please be as precise as possible. Ideally, the title would contain the action/card combination that causes the bug, and the text a detailed description of when with pictures as proof. If you don't know how to take screen shots read this
http://www.take-a-screenshot.org/ It does not need to be perfect, but bugs cannot be recreated nor confirmed without enough details.
Thanks for reporting bugs!
