At some point, and it seems that this is directly related to either the amount of times that you go into the contracts screen and scroll through the current contract, or swap contracts and scroll through the alternate contract.
The contract screen’s control disappear and none of the controls work except for the touch pad which will dismiss the screen. You then need to press the touch pad again to access skills, inventory etc.
You are however able to touch pad and then navigate to the contract screen and then claim a new reward, however I suspect that this is because a new view is placed ontop of the contract screen. Once you have acknowledged the new reward you cannot scroll back to skills etc. You first have to exit and then touch pad again to do something else.
In order for this to work again I need to log to title to get this working again.
