slot object didn't work with mesh

[anotherREYY]

i have created a sprite object filled with meshes instead of textured planes ,and merged them to a slot object . they switch fine when i changed the index trough the slot index's slider , but when i keyframed the slider and playback it , nothing happens , the slot object mesh didn't change , eventough the keyframes do appear on the timeline . no errors are reported .

if i use textured planes it worked fine . but it wouldn't work with meshes , is there any solution for this ?

Could you share a test file. That way it'll be easier to evaluate.
