Hi i returned from long time back into game, when i pressed on my pet dog it said: you want to queue 0507? Or something like that, then i put yes. And it dissapear, wtf?
ctrl+A >> interaction tab >> dog icon (Pet interface)
there are about 20 slots (to hold pets) but only 10 can be used.
if you have more than 10 pets you will not be able to activate/ call out the 11th pet unless you remove one from the pet interface and replace it with the 11th one.
you can still hold/keep individual pets (whistles) in the warehouse or bank.
