Dear ,maybe you did not watch video till end where I set my fireball vase to -20.Is very close? Would you like me to post another one that If i set it to -100 it will still do same? is something that did not occur before latest update. system registered even 0.01 Z order changes and I had zero issues with stacking order during playback so yes is a very serious issue at least to me and who knows maybe to you as well, later on.
I noticed if I make one of my sprites a translucent material, it always gets put behind masked sprites regardless of Y axis order. I’m not sure if is same issue you might be having…
