>Description:


Quoting Harry Coin
"Otherwise if resource_xxx lookups get called while still in static hints mode, and hintmode is 0, then after going to dynamic hints mode hintp_ is not reset, and so the res_xxx routines only still look at the static hints, they don't get any of the dynamic hints that are new or changed."
