Can't find anything on forums so have no idea if this is a known issue, but several of the values on westemnet relics are not scaled correctly, a screen with some examples:

A mess, and not only on the tooltips: a kinmember with the westemnet setting on their bridle checked by slotting/unslotting the bridle, and war-steed strenght does indeed increase by only 20 and not by 40.
Hope this is a known issue (now) which will get fixed soon!
