Mission quirks
Was in an indoors style mission a couple nights ago. Some of the rooms were fair sized (just a little smaller than entry rooms) and had 2 levels to them. In these cases, the pets seemed to get a bit confused, running off in various directions before eventually finding the correct path. Perhaps the node placement for these room types needs another touch up. The particular 2 rooms that come to mind were square and had sunken centers.
Room A had 2 doors situated near the corners. There were L shaped ledges you could stand on (at room corners) as you entered either door. Each L shaped ledge had a stairway down to the large sunken area.
Room B had 4 doors with a smaller sunken area. The doors were in the center of the walls. In front of each door was a stairway down to the sunken area. You could walk all around the room, at the outer perimeter without ever going down. In each corner, there was a reasonably large area that was on the same level as the entrances - i.e. not sunken.
The mission was QL60 in SW Andromeda.
Temple quirks
The entrance is a problem in the Temple. The pets get stuck in the door sometimes. Also, if the pet spawns in the corridor off to the side, there will be a pillar a couple meters in front of it. If you go running down the hall, the pet will sometimes move forward to follow, hit the pillar, turn around, hit another pillar near the door, turn around, hit the first pillar again... I watched it do that for about 90 sec one night. If you go back near the pet, it can then find a path to you.
I noticed another quirk up in the northern section near Nematet. That area is a large rectangle with cultists along the outer edge and another rectangular room embedded in the center. In general, I enter and head west (clockwise) - the quickest way to the entrance to the embedded room. One day, I was feeling leisurely and headed counter-clockwise instead. I tend to select a target, give the attack order and then select the next target while the pet does the job - easy soloing here. When the pet's done, I give the next attack order and then loot the recent corpse. As I headed north, I had picked off any cultists on the east wall and was working the first couple on the north wall.
I found that if I stand be the wall to the embedded room (south of the northern edge of the embedded room) and give the attack command on the mob on the north wall (west of the eastern edge of the embedded room), that the attack pet chooses to go the long way around the embedded room (clockwise) instead of taking the far shorter route counter-clockwise. This will happen if the pillar at the corner of the embedded room is between you and the mob.
In an added little quirk, the heal pet once began to follow the attack pet the long way (clockwise). But it stopped prior to reaching the southern edge of the embedded room, waited, and eventually turned and headed counter-clockwise to meet the attack pet at the targetted cultist.
It looks like the attack pet prefers clockwise movement to find a path and the heal pet prefers counter-clockwise movement.
