delay closing (~4s in ish)

SUMMARY
When opening/closing kickoff, quite frequently there will be a delay before it begins to move. Whilst moving, the animation also isn't very clean and stutters a lot.

STEPS TO REPRODUCE
1. Open kickoff

OBSERVED RESULT
Stutter + delay

EXPECTED RESULT
No stutter / delay

delay opening, first open

Didn't make it clear, but you can observe it with mpv & by pressing "," or "." to move one frame at a time.

Video looked fine. There was no 4s delay

Recording of me steeping through a recording of kickoff opening

Sorry if I didn't make it clear.

I meant 4s into the video.

I decided to record myself stepping through the video to show the issue:
- it takes 9 frames for kickoff to begin opening
- the 10th frame kickoff is 3/4 open and it stays there for another 2 frames
- next few frames it moves the last 1/4 of the way smoothly.
