But I was kind of getting used to the Dark Kerbals (flashing eyeballs)...

I agree on the pricing. $50 is real money and approaching finished game pricing. It's not like the publisher is some group of starving devs out on their own, but instead a multi-billion dollar company. It's hard to see how they can ask for more that the KSP 1.x cost for a 2.0 alpha that doesn't even come close to supporting the 1.0 features (let alone the perf issues).

I just loaded the mod. The only handrail that shows up in the VAB is the 2mR. I'm guessing that all the other hardrails are not loaded so any ship that used them won't load.

I'm on 1.4.1 and get the same error about the "food" tank. Do you have Kerbalism installed? I do and in my case it seems like some sort of conflict between B9, Kerbalism and SSPXr. Not saying this mod is at fault, just these three together result in the error for me. Eventually I had all three working together by going back to an older versions of Kerbalism (1.3.0.2) and the non-upgraded version of B9 that is included with this mod. That worked for me. At this point though, I've uninstalled Kerbalism since my box keeps locking up after a successful app launch and I'm trying to isolate the cause of the problem - maybe too many mods...
