I am getting this message in my console when i upgraded to Pixi version 8.12.0. "PixiJS Deprecation Warning: Please use container.collectRenderables instead. Deprecated since v8.7.0." I am using "@esotericsoftware/spine-pixi-v8": "4.2.89".
I tested this with an empty new Container., and it happens when i use spine.addSlotObject(slot,container)
My guess is this is new consider 8.12.0 is only a couple days old.
Thanks
