I've made a couple of tests with and without VR here today. First, there is no problem at all on a flat screen, and the bug occurs only in VR.
I was at EBBR ( Justsim), gate 146, pushback facing north ( PB customised by myself) .
I confirm that the problem stands in VR mode. More precisely, I think there is a bug in the VR menu, when you are asked to click on the direction you want, you get stuck.Then, if I switch back on the flat screen, and if I interact with the menu (on the screen ), everything works fine, go back in VR and I continue the pushback .
