How to get past Worgen Exodus quest with phasing bug

If you are playing a Worgen and make it to the quest Exodus where you are asked to board a carriage below Greymane manner, you may end up with a phasing bug that only shows a floating harness instead of a full carriage: https://i.imgur.com/0ilZ3a0.jpg

1. The first thing you will need to do is submit a ticket for the GMs to make the quest complete for you. However, once complete, you may still be trapped inside the courtyard until you can get to the carriage's location to speak to Prince Liam to officially mark the quest complete.

2. After you get a message from a GM it is marked complete, and if they did not teleport you outside of the courtyard, you will need to open the Help window and use the Stuck option to kill yourself while standing at the closed courtyard gate. You may have to do it twice, the first time may just teleport you back to the king.

3. Once you are dead, you will appear in the water as a ghost. You will then need to start the trek south as far as you can go toward Prince Liam. However, you will not make it all the way. You will eventually hit an invisible wall. Then press the option at the top to teleport to the graveyard. You will then appear near Prince Liam where you can ask the angel to res you. If you are lucky, you will res right there and and complete with Prince Liam. If not, it will res you back where you died in the middle of the water.

4. If you ended up back where you died in the water, then it is time to start swimming north. Yes, north. We can't get to Liam southward because of the invisible wall. You will swim around the northern part of the island until you come across a place to climb up to land.

5. You will make it to where the Headlands start and see a ramped path to move up to the land: https://i.imgur.com/xZuCZ66.jpg

6. Once on land you will need to continue up and around the northern part of the island and back down south until you make it in to Aderic's Repose (check your map).

7. In Aderic's Repose there will be a house next to a pile of flaming bones, you will need to go into this house: https://i.imgur.com/vadhHbk.jpg

8. In the house will be stairs leading down into a tunnel: https://i.imgur.com/VLvQZ35.jpg

9. Take this tunnel all the way through and you will end up in an empty Gilneas City. Then follow you map to Prince Liam (the question mark on the map) and make the quest complete and then carry on per normal. If any gates are closed along the way, you should just be able to click on them an open them, unlike the Greymane Manner courtyard gates.
