Is there anyway to prevent this nuisance from terrorizing my replays?

I just made a replay that took 35 minutes to look right and then when I go to finish my glorified work it skipped and I was like...

No.
And then proceeded to stare at the screen in disbelief.

It happens when you edit your replay a lot. To avoid this, make multiple saves of the same replay while working on it. That way, if a replay skips, you can load another one and work on it.

Also, I do not know any fix to this problem.

What do you mean "it skipped"?
Did you mean it started a new game?
If it is, it usually happens to ver 3.91.
There was a space fixer script made but it doesnt actually solve the problem of "auto-new game". It just avoid pressing space twice at the end.

I should say use 3.90 or lower to avoid that bug. I already reported it in support but let's wait for the next release which would be ver 4.0

also try :
go to option, enable auto save replay, but its kinda annoying if you play in multiplayer without disabling it coz all the matches will be saved

Oh...So that's what's been happening.

Thanks all, but I'll use Farid's great idea when I make single Player replays from now on~
