Pet problems + multipet

Multipet.

The pet you select as "boss" will pick up the items/mesos. The others, if aren't equipped with loot equips, do not interfere in any way.

No, not necessarily. You have 3 sets of pet equipment. For a while, I had my pet equips set to the second pet. This meant the Boss pet and Tertiary pets did nothing, while my secondary looted. It works well because the Secondary pet is placed in front of your character, so for a ranged person the secondary pet will walk over the drops before your character does. I was getting annoyed with something that happens when you get near edges, though, so I ended up setting the looting equips back on my boss pet.

With 3 pets, any 1 pet equipped with looting items can loot, regardless of whether they are the boss pet or not. Also having the other 2 pets with no looting abilities does interfere sometimes, but it's never been a huge nuisance to me. I have problems with my pet looting mesos (it treats them like they were from another person's kill, and by that I mean the pet runs up to it and waits, and will grab items near it, and after about 30 seconds will finally be able to pick up the mesos.) In most cases I end up picking up the mesos myself, but once the pet passes by it seems like the inability to pick them up passes on to me as well. Once in a while the pet looting will start working great, like before, but then goes back to the glitched state.
