Here is my situation:
A monster play "idle_anim" on track_0 in normal status,
sometime monster play "eggstatus_anim" on track_1 to enter egg status.
Its hard to explain why not play "eggstatus_anim" on track0 . but its whats happing.
So "idle_anim" hide eggslot on start playing , and "eggstatus_anim" show eggslot on start playing.
Then the egg will flash, because the eggslot show by track_1 and hide by track_0.
My pseudo solution is when upper track playing, stop update the visibility of slot in bottom track,
and on upper track clear, adjust the visibility of slot to match bottom track.
I findout the visibility of slot is affect by _spAttachmentTimeline_apply, however, i dont have enough ability to fix it 🙁
