Severe game breaking bug for rangers.
You don’t have 3. One is for underwater combat. The bottom 2 slots are for undwater
You can also have 2 pets active at one time so when one dies they switch out or if you want to switch them out you can during combat. So that’s why you see it switching “models.” You are hitting the f skill or whatever it is (small arrow near your pet bar) that switches the pet.
