Hello, in my campaign part of the tournament we completed episode 5 and the campaign ended giving victory to my opponent (4-6).
Can someone explain this rule to me which I haven't found anywhere?
Thanks in advance

Tournaments have a maximum time limit.

The tournament time limit has not been reached (the other games are still in progress) and we each have 6 days left.
