People are frustrated with a bug that breaks progression. I mean, unless you are responsible for the bug, or fixing it, don't let people voicing their opinion get you all wound up.
Here we are a few weeks later, and they are still working on a fix. Well, like others have mentioned, move the exit star so that those of us wanting to progress - can progress. It seems ridiculous to have a bug like this on a main story line. It seems ridiculous not to have a hotfix moving the exit star to a point where we can move on to getting our skyscale mount.
Oh, and guess what? I am also unable to complete this because of this annoying bug.
