This really should not happen and I highly doubt it has anything to do with my profiles. Please provide a log ([post=378165][Guide] How to attach your log[/post]) so I can take a look at this nonetheless.
The way my sales mechanics work is that the profile only modifies sales for items that do drop in those raids. It is basically whitelisting raid loot for vendoring from the specific dungeon you run if you can't wear it and it is done based on the item id. Anything else in your inventory is basically forbidden to be sold. There are general problems with sold loot where items are missing from the protecteditems.xml, but, again, this has nothing to do with my vendoring techniques. Still I'd be happy to take a look at it, provided you add a full log. Have you had issues like this e.g. when questing through Kick's profiles? I have been wrestling with sold items at the questing front myself.
So you want it to leave the instance through the entrance? I don't know if that is feasible. In Sunwell Plateau it is impossible, because the way is blocked and even if you were able to do it, you would be stuck on the Isle of Quel'Danas and would have to fly back out to Silvermoon/Ironforge which would take longer. Leaving BT also takes quite a long time, because the dungeon is so large. Then flying to Shattrath hardly seems like we would gain time though I haven't measured it. And going from Hyjal in the Caverns of Time back to Shattrath manually is a tour around the world. If I am misunderstanding what you mean, then please elaborate.
Most of my characters have their hearthstone still at the shrine and maybe I should prioritize using the normal hearthstone before the garrison one if it is bound to shrine because with the portals in there, we could get almost anywhere real quick. What do you guys think?
