There is a small typo in the config file for Habtech 2. it was causing B9 to error out.
Line 1790
-B9_TANK_TYPE[ht2_02]:NEEDS[HabTech2,B9PartSwitch,CommunityResourcePack,!ProfileNone]:AFTER[zzzKerbalismDefault] { }
Should be replaced with
@B9_TANK_TYPE[ht2_02]:NEEDS[HabTech2,B9PartSwitch,CommunityResourcePack,!ProfileNone]:AFTER[zzzKerbalismDefault] { }
Typo with the first character.
