Somehow HB2 turns out to be cheaper to build than a HB1.
Further only HB2 needs TRU, the others not, oversight?
With this adjustment the mixed Habs (HBB, HBC, HBM, HBL) are now more expensive, and I fear that they will not be build at all.
Maybe @Counterpoint can look into this sometime?
If and when it gets looked into maybe consider adding other Construction Parts/Materials to the cost.
A HB4 and HB5 could do with some DEC in addition to the TRU.
