Next version... next fix.
I'm not sure exactly how your game got into that state, but the next version will nuke and reset some internal data and make sure all the right structures are there (fingers crossed)!
@Cassian - You're reporting a completely different problem, yet could be fixed by what I'm doing to fix the above. If 0.7.11 does not fix your problem, I'll need your save file in order to reproduce your errror.
Both of these errors are suggesting your game save got into a state that I can't replicate. It could have to do with other mods you are running, or a series of steps I'm not thinking about.
