Error: LGB-10C data block is one ton underweight, adding up all masses listed by hand and entering the 'Mech in SSW both show a total mass of 84 tons.
The Correction: The 'Mech is pretty critpacked, the easiest solution is converting the two CASE components to CASE II. That will raise the tonnage by 0.5 each, filling in the remaining missing mass.
