Had a really odd error today. Sent in a ticket but was curious if anyone else had seen something similar. I was adding ferro-fibrous armor to my Treb when I got an error saving the mech. When I went back in to reapply the upgrade I saw that its price had increased for this mech and every other I owned without ferro. However it still costs the same to remove it from those that were already upgraded. Relogging, restarting client and repair tool do not fix.
