The particle effect 'game-over-stars.prt' uses the 'icon-star' texture in the texture atlas, but this does not get overridden by any resource packs present.

I.e. if a resource pack overrides 'icon-star' in it's atlas, the three big stars use the new texture both on the game over screen and the level select, but the particle effect still loads from the default texture atlas. (Editing the default texture atlas with a third party program confirms this, see attached screenshots) I haven't confirmed if this happens with any other particle effects.

I've included a .zip of the resource pack I tested this with. Maybe I'm just creating resource packs wrong?
