Why is this animation not working as intended?

Question

Hi there all the past couple days now I’ve been trying to modify the iOS tweak Daisy. I have successfully added more fonts, make the Hello animation stay on the screen and merged a closed pull request that the original dev didn’t want In. Anyways I’m up to trying to fix this bug that the original version has and that is that the “playHelloStartAnimation” will bug out sometimes when waking the phone. Sometimes it will fully replay the animation from the beginning or a couple frames from the middle of the animation, other times it will finish and show nothing for a few millisecond and then continue to the next animation or will play as intended. Tried adding a blank animation to play first so when it dose bug out you’ll won’t see but didn’t help, change times, tried other hooks still happens. Can’t figure out why any help would be appreciated.
