I'm not seeing an issue happen after incubating a pet either randomly or for imprints. Nor after rushing, claiming and equipping the pet. Also tried copying Das_Maning's account since they hit it most recently, and their account works fine for me; there's a puppy ready to claim, and Helminth works whether I look at the puppy first or not. The fact that it sounds like the problem fixes itself after you relog probably means it's very specific to the order of what actions/screens you are using. Would love to get this fixed for you, but gonna need more details about exactly what people are doing, or especially video if you have Shadowplay available to show the steps leading up to Helminth becoming non-responsive.
