Your function returns nothing. Remove the semicolon so that S = SparseArray[lis2, {size[[1]], size[[1]]}, 0] + A.

comment How do you handle upgrade frequency now that minor releases come so quickly?
My preference (since 2.2) has been for a premier subscription and have updates when and if they're ready. YMMV.
