Need to know details of your rig - what the guidescope and camera were.
If this was guided with the little 30mm ZWO guidescope, I am not surprised.
I use a ASI2600MC DUO guiding at 254mm MCT 3000 mm focal length and I have never, ever seen values below 0.2 arcsec.
When the guider shows insanely low guide errors this only means the guiding errors are smaller than what the guidescope can accurately measure. Bear in mind you are using a guider that cannot resolve any better than 3 arcsecs.
