Focal neuropathy

One of the lead wires to a pain sensor must have caught on something as A.s.a. Moved one of its mobile arms. This lead tore free signaling damage where there actually was none. This has resulted in A.s.a. Favoring the use of its other arm. (Which then had a higher recorded utility for the actions it had taken.)

More pain sensors

It is difficult to mount A.s.a. H.'s pain sensors on moving parts. In the case of Lego beams connected by a pin or axle it may be possible to mount 2 thin metal washers between the 2 beams, one glued to each beam. As the beams rotate (through small angles) on the pin the washers maintain electrical contact and the lead wires flex slightly with the motion. Should the rotary joint fail the damage will be signaled.
