I can build stairs down. And I place them within the influence of a power pole connected to a generator. They have enough electricity. But when I walk over the stairs down I don't go anywhere. And if I attempt to pick up the stairs (mine them) I get a weird Lua error about having tried to index something with the key 'proxy' and not finding it. My game then exits.

I'm apologize, in my haste to get out the last hot-fix I ended up mixing my branches and broke the whole thing. v0.3.5 should fingers-crossed fix this. I'm testing it tonight multiplayer and will push another patch if necessary.
