There is a bridge in COA where there are three sets of mobs and more mobs start to add in from the next area as time passes.
I have crashed here every time I have played COA since the TG patch. I have crashed more than once for each instance. I have crashed while healing and while tanking. Other players in my groups have also crashed (but perhaps not each and every player.)
This is not the kind of crash that leads to the ESO error report pop up.
