Its not slow wittedness, exactly how many of the 16 will have actually used the fan patchs? I know I was one of em, and ive never used the patches, so how could they help.
Further, how many of the people who have actually used them and checked have actually had that problem, probably not many.
So your left with 16 people who need to figure out how to solve a problem they havent had and dont have, which takes a thing called time, which exists in periods above and beyond that of two days.
