That's strange. I remember someone else getting weird default bindings with a DualShock, but nothing about spinning. It does remind me of a bug I had years ago on another game with a cheap old controller, but it feels like a long shot from there. Go figure. I didn't do an in-game rebind menu because Unity infamously doesn't support rebinding at runtime with the default input manager, which my input relies on (namely the nametags). What I could do is make it possible to switch those nametags around.
Sorry I'm so late to the punch.
