I have heard from several people that since the last patch, you freeze up when zoning with a hireling. Well, it's not just when you have a hireling for me. I have been freezeing up when zoneing for 2 days now. I can not even do anything in 3 barrel cove. Every instance I have tried to go into there has frozen on the loading screen. It loads very quickly but just sits there at a full load bar and doesn't zone.
I got fed up with it and switched from my rogue to my fighter and all was going fine, did a few good instances until I went to the steamvaults in the marketplace. It took me 2 tries to get into the kobold blockade instance, when I finaly finished it, went to the next one in the chain, forgot to put away the hireling, and froze again. Relogged, went back to the instance without the hireling out, and still can not get into it. 5 tries so far to get into the instance and everytime it freezes on the loading screen. As I said all was fine in other areas, but it seems some zones are not loading for me.
For the last 2 days it has been cross your fingers and hope you zone. Being a weekend I was hoping to find groups and do some of the quests I can't do solo even with a hireling, but sadly I am now to afraid to group up as I might not be able to get into the instance and I don't want my charaters to be labeled as "unreliable". I hope this is fixed very soon as I am stuck right now between not being able to do quest because of the bugg or I need a group to do them.
