After Lee has been Bitten, select 'Hide' or 'Show' on his bite, all 'Choices' cannot be select.
Previous steps were quitting via the XMB after selecting 'Show'.
We made the wrong choice to we quit and and reloaded.
After this, no matter if you re-boot or quit the game we lose all functionality of the Choices :(
PS3 version btw.
Really upset with this, can't believe an issue like this can be mastered!
