Crashed 6 times on Savannah, anyone else?

Had very little crashes since launch and they all are just straight up the game closing.
Today had this problem with this instance in the image.
If I stay in at the start, not exploring the map, no problem.
As soon as I find any enemy and start fighting, the instance crashes.
Kept trying different things to try and find what was causing it, and even if I don't attack, after 1 or 2 seconds after I find enemies, the instance crashes.
Anyone else got any similar problems?
Map was a T16 mistakenly used on a +1 no boss zone.
