I am Playing a Beastmaster and have the Claw equipped. I use one Crow (Winged Raptor) and multiple Wolfes and whenever I change the level, use teleport, etc. I have X + 1 Wolfes instead of X Wolves + 1 Crow.
Also when I summon the wolves first I can’t summon the Crow, but I can summon any other companion and it successfully replaces 1 Wolf.
I don’t know if it has to do something with it but with Winged Raptor selected I can’t Summon more than 1 Crow.
