Ok for the Non-VR oriented Beta of 0.952, the flapping animations now should work correctly. This is set for the Beta option in Steam as it is as-yet untested for VR use. Stick with 0.95 if you're a VR user for now. :)
If you're a non-vr player, opt in to the beta to get this version under test and give it a go. I'm currently uploading a video showing some demo gameplay in 4k 60fps, but it's taking a small age to process. Once it finishes, I'll put it here in the Steam page of course.
Very small update ... less than 1mb for either the demo or full version.
Thanks for your patience. :)
