This bug has bugged me for months and months and…
I’ve reported it in game almost daily, made and added to topics on these forums and then finally gave up and just vowed to never die so the runes wouldn’t break.
And now I see it’s fixed! My vampy necro sincerely thanks you ArenaNet for finally fixing this pesky bug.
