Have you tried deleting your save files folder located at 'C:\Users\{username}\AppData\Local\USS'? If not, try it and see if it fixes it, if not - wait for the update. I wasn't able to find what's exactly causing this bug in this build, everything works for me no matter how many times i playtest it. It can happen if your character is wearing a cage, try to remove it and see if that helps.
