What is the support ppc bv suppose to be? Was there recent errata on this? Techmanual recent reprint i got shows 14. Megamek shows 12. In fact shedu ppc battle armor comes in at using a 12 bv sppc in megamek AND the mul matches the shedu calculation too. Which would make one think that 12 bv is the correct version. Clarification plz, thx
