gimbal lock with ofEasyCamera / setTarget

I’m using ofEasyCamera. I set an initial target, and I then set subsequent targets. I have enableMouseInput set so I can orbit a point. It works as expected on the zeroth target, but the instant I change my target, my mouse input is all fubar’ed. Ive attempted to set orientation, reset once setting target, etc, to no avail.

Is this a known issue, any ways to stop gimbal lock from happening when using mouse input?
