The Glyph of Savage Roar casts a different Savage Roar spell than the normal finisher spell.

I don't know what the best way to indicate this information to ABA.
I added the following to rules/Druid.lua which produces the desired behavior in-game.

BuffAliases {
     52610,  -- savage roar (normal finisher)
     174544, -- savage roar (buff from glyph)
}

This already has been fixed in development. This should make it in next release.
