I've found a couple of Exception Errors that seem to be a combination of Missing History (v1.7.3), Kerbal Atomics (v1.0.2) and the associated KerbalAtomicsLH2NTRModSupport extra, and Real Plume-Stock (v1.3.1).  I think the MH LH2NTR patch in KA is the culprit. - I can run MH with Real Plume without any errors. - I can run MH with RP and KA without the LH2NTR patch without errors (I figured this would be the same as above). - I can run MH with KA and the KA LH2NTR patch without err
