Found this issue in a project im working on and was able to reproduce it in a clean project, link below.
If you have a level sequencer with camera cuts etc with multiple keyframes, the lerp for the camera between the keyframes changes if you move the last keyframe.
As you can see in the video, i have 4 keyframes where the camera moves between them, at first they move perfectly as intended, if i move a keyframe in between (not the last one), they still move as intended. But if i move the last one, the lerp to the Second to last keyframes is different, it moves, then freezes for a little bit, then continues to the last keyframe. This happens, even if you move the last keyframe, then move it back to where it was.
