Thanks Thamis.
At the moment, SotM is in a sort of limbo. The history at this point is a little convoluted, but, basically... We made the decision about two months ago to come up with a new design, as our old project lead, JBG, hadn't been around for quite some time. To that end, I had to court and enlist the aid of a friend of mine who is particularly knowledgable in the area of real-world lunar colonization technologies and issues (an area about which I knew very little at the time). He and I spent weeks going back and forth on what could be done, what had been done, and what we might want to do. What there was to model and how to model it. We had just finished thrashing through everything and were starting to go back to take all our disjointed conversations and piece them into a detailed design document when first I got buried in taxes, then he got buried in a product release cycle at his place of employment. Theoretically, he should be come free of that next week, although I have some concern that he may not really free up until the end of May :/.
Until our new design document gets done we have the problem that while Woodelf and I have a lot of ideas of things we would like to change or improve, we have no coordinated plan. We surpassed the level of detail in the original design long ago. This left the mod careening directionless, which compelled us to create a new direction. The crafting of that direction takes time. Neither Woodelf nor I want to put in a lot of effort making changes to the mod that we're just going to wind up throwing away.
Now, there were a number of feature ideas I had that I wanted to test out, which I haven't been able to, because I can't seem to get anyone to provide me with the things I need

(buttons and features and the like). In that absence I've started working on other projects, and waiting, as I think has Woodelf.
As for crashing after getting a particular tech, I've never heard of that bug:/.
