I created a single elimination tournament that was set to begin Dec 26. It allowed for 2 extra days before being deleted. For some reason, it seems to have created "double" tournaments in some of the games. For example, Frog Finder. There is one version that has 4 people. Then there seems to be another version that has 5 people. When you go to it's main tournament page, where it lists all of the games of the tournament, it is only listed once of course, and if you click on it, you see the version with 4 people. (Not the "extra" one with 5 people)
BAH HUMBUG!! #3 is the 4 person one
BAH HUMBUG!! #3 is the 5 person one.

EDIT : Oh, it seems to have created at least 2 tournaments with the same name, but different tournament #'s of course
BAH HUMBUG!! #3 (#46532)
BAH HUMBUG!! #3 (#46491)
