Not likely. It's common for LRU's to be 'pin selected' for different configurations of the aircraft. On some aircraft, it's literally done with programing pins, but on the newer stuff it's typically done with a software key. All it took was for some engineering work to have been done on the FQIS that was not done correctly.
Hard to believe that this aircraft had been flying around for years with a 41 ton weight discrepancy that was never noticed...
