Last week I purchased a dragon pet, and I notice that when I've been browsing the CS for a while, when I leave the CS window my pet is gone. I don't see it anywhere yet its still equipped. When I asked my buddy he said he still sees it. I can also see it if I look in my inspect window. But when just looking at the room, the pet is gone. So this is apparently a bug that only affects my view. But still a bug as I would like to see my pet. The only way to fix it is to either leave the town and come back, or to un-equip and re-equip the pet.
Also, this only happens if I've been in the CS window for a while. If I'm just in there for a minute or two then no problems. But if I'm browsing listings for 5-10 minutes, then it happens.
