I decided to run a PTS character through the Main Quest and I've encountered a bug that halts progress on my Main Quest. On the quest step in Shadow of Sancre Tor "consecrate the shrine in the dragonguard tomb." I can interact with the shrine, and Sai Sahan has his lines, but it doesn't actually complete the quest step. I haven't yet tested it out on another character, but this kind of bug can prove to be quite bad if it makes it to live.

I've left and re-entered the instance, reloaded UI, nothing changes. Anyone else have an idea about a fix? I've also reported this using the in game function but I wanted to post this here as well.
