Can you please post a replay of the "bug" so we can check please.
To make and post a replay:
At the end of a duel it ask you to save the replay give it a name like Six Sam bug or something so you know what it is.
Then make a post on the forums saying this what it is and above where it says: Preview Post Cancel

Click that option and then click post it will then change to a different screen and ask what to attach, find your file and stick it in and it should attach to the post you make.
