Guild Wars 2

My guild has the gilded hollow as their guild hall, we unlocked the guild music.
We can’t seem to put “The music of the caverns” as the standard song, every music of the cities seems to work, but this never stays, it plays when i purchase it while in the hall, but it doesn’t stay.
Is this a known bug and is there a fix? and if not, were developers aware of this bug?

During the final part of the norn story line “Code breaker”
at the section where you get to chose which of the 3 factions you want to go with, there’s a part during 1 cutscene where you hear the voice of the priory person while you see a different text and the vigil person
Also, after picking for the vigil, during the conversation the characters were standing as if frozen, only their heads moving when they spoke.

not any major bugs, but slightly off putting while following the story.

I was kind of curious of the devs if there’s any future plans through expansionpacks or updates that the Koda and I believe they were called the Tenshu (the bird people) will ever become playable?
I love to current races so far, I love their indepth story lines and I was highly surprised by the depth of the Norn story line with the Jotun section in there, it was very interesting and I was hoping to see more like that with those 2 races together with some new classes maybe, just curious if these things are on the devs minds, not asking for complete confirmation or a time stamp or anything.

thanks in advance.
