Thanks for the reply. Unfortunately this project doesn’t actually have any C++ code. I probably shouldn’t have posted it here, but I figured the coder forum was the best place for an ambiguous debug message like this…
I’ve pored through all my blueprints and whatnot, and not found anything that is using rotators at all, so I can’t see where this is coming from. The only rotation I was doing was to reset the HMD yaw to 180 degrees - deleting and recompiling that part of the level blueprint hasn’t had any effect
