ClosetGnome_Mount has GratuityLib in its X-Embeds. But I can run it just fine with LibGratuity-3.0 installed (disembedded). No idea if that is something that should be "upgraded".
Because LibGratuity-3.0 fools AceLibrary into thinking that it is Gratuity-2.0 as well.
Actually, it looks like CG_Mount never even opens GratuityLib. Can it be removed from the OptDeps/X-Embeds alltogether?
