I'm not sure if this is a known bug, but I have encountered it occaisionally, and it happened to me just before.

I made a really smooth and stylish single player replay and saved it, I went into toribash about an hour later and tried to open it and it was jumpy as hell, as if when it waas saved some of the ponters in the replay weren't saved. And it was singleplayer too, so lag couldn't have done it.

And I have a brand new homebuilt computer now, so it isn't due to low FPS either. Can anybody help?

it glitch? it happend same to me and when i ask support it cant be fixed they said its because to many editing on the replay

Well, I did edit it alot, so that could be a problem. Do you think they will fix it maybe?

i think no they said it cant be fixed (as far as i know becoz i did this before)

No, I don't mean the replay, I mean the bug itself.

No, I doubt if the bug will be fixed. It's not easy to find out why that happens, but sadly, it does.
