Gosh, i hate it. i hope, some of you Guys can help me out. Everytime i try to make a cool Singleplayer Replay, doesn't matter which mod, there are some random restarts, mostly on the best points.
I tried so many times to decap uke in Capoeria, then i got it, and 2 rounds after the decap it just made the fight start sound and i was staring at a damn new fight, just like i just started it.

Someone knows the reason or can help me out?

Hmm maybe if you used Shift space or pressed E and it was at a random frame such as 392? That's when it normally happens to me, after I use shift space.

It is just 3.91. It so buggy. It does it to me all the time. Don't even bother trying to download 3.9 or 3.8 because it just downloads the 3.91 installer. If anybody has the 3.91 installer can you upload it to a download website and post the link please.

It happens to me very often as well,
esc->setup->options->Autosave replays
Whenever it randomly restarts just fetch the replay from the autosave folder.

why dont you press r when you reached the frame to 10

When you are making singleplayer replay, Save it quickly if it is a good one.

Save now or suffer later.

I always click space to many times and loose my replay : (
