As far as I've seen.
Another bugs:
-Escort Caravan Thieves can't be killed.
-Liu Soo's Plea(Maternity Nectars) won't appear.
Comeback bug:
-Mount Auto-Path Glitch(Stow)
You need to be in PK mode to complete the Escort Caravan quest.
Auto Path mount bug is a PWI bug which cannot be fixed, if you are ever stuck like that, use a teleport stone to teleport somewhere.
I'll be doing Liu Soo's Plea soon, don't yet know if the quest is bugged after the patch.
