Ever since the parity with cubic easings in the preview and in-game were fixed with curved animations it has unfortunately introduced a new problem which affects all animations both in the preview and in-game.
Constant keyframes in curved animations now seem to interpolate as if they were linear and there really isn’t a work around for this, even if you were to group the keyframes as tightly together as possible you can still very noticeably see parts moving around just very quickly.
To reproduce the issue just simply make a curved animation using constant keyframes and you’ll see them moving around really fast instead of being instant.
Expected behavior
Constant keyframes are supposed to be instant.
