sorry, i meant to say you need to make all edits in animate mode. yes you were in animate mode but that was after editing which will reset the particle on animate button press.
Try this:
> Add entity to scene
> Add particle action
> Animate the scene
> Now change the textures to the animated tex.
> Press save and exit animate mode
Edit: We initially did it this way because it makes sense to edit effects while you can see them lol
