I’m having an issue with Spriggan. If it is assigned to a regular hotkey, then after summoning the ability swaps for the companion ability. If it is assigned specifically to RMB, it doesn’t and I can only resummon the Spriggan somewhere else.
This issue does not affect Wolves, at least if you have The Claw equipped. You will summon Wolves until you have two, then the companion ability swaps in as expected.
