If anyone knows how to fix this I would be so grateful!
It has happened to nearly every curve i have created. Even ones I havent touched since a previous render.
There are more spikes than frames. So bizarre. When i go back to previous saved files it is on them too.
Pulling my hair out ☹
I don't know why that's happening, but a lot of times, the keyframe interpolation interpolates a little more than I would like it to, so I select the two keyframes, right click, keyframe interpolation, and set everything to "linear." That tends to get ride of any weirdness, and then I can go back in and add a curve that behaves a little better with the graph editor.
