'Sloppy' is a bit imprecise.
The Lynx has an artificial feel system to provide force with displacement, and if memory serves me right, cannot be turned off. So unless something fails in the artificial feel system, the forces on the controls will always be the same. There should be no sloppiness associated with just the controls - if so, it would be there all the time.
The response of the aircraft to control inputs can be less than precise, however. This is probably what should be looked at. This can be caused by a less than well behaved AFCS or less likely, looseness in the mechanical controls. Looseness in the mechanical controls (worn bearings, etc.) would be evident all the time, where something not right in the AFCS can be temporary.
Also if flying at high altitudes, the Lock number effects on the controls can cause unanticipated reaction from a control input - a fore-aft movement will have some roll associated, for example.
More details of when the 'sloppiness' appeared are needed.
