Concealment.

Turns out that I broke concealment when I was trying to fix something else. My bad.

It's now fixed. For real this time.

There's some sort of issue where when a grid is concealed, all the armor blocks stay behind, but they have no physics; you can fly straight through them. I'm pretty sure this is a problem with SE, but I kinda like it. You can still see concealed grids, but the server isn't processing them. Best of both worlds.

However, it doesn't reveal grids with medbays when you load in, so you won't be able to spawn if you let it conceal grids with medbays. Fair warning. I'm working on it, but I figured I'd publish this now; concealing some grids is far better than none.
