One piece of errata on the Knight OmniMech it says there is Clan Ferro Fibrous on it but no crits are allocated in the space requirements.
That's intentional, actually. I was putting the sheets together and on some of the units structural components were taking up 10+ lines, so I tried leaving them off to save space.
Looks pretty impressive although the text is screwed up for me.
Which parts of the text? What PDF reader are you using?
