I'm not sure if this was posted somewhere else or if this is the right place to post,but sometimes when I defeat Uke,instead of showing the replay,it just starts another match against him.Is this a glitch/bug?

This is a known bug.

It somehow skips over the replay and starts a new match instead.

If this becomes a problem for you, enable the option to autosave your replays so you don't lose anything.

Ok,thank you.

Closed.

Without the autosave feature; There is another solution. Just before the match is about to end, save the replay. You will miss some part of the replay but it is better than ending up with nothing.
