Looks like the last update broke it for some people. I can't replicate it on my machine, though.

I've rolled back a few of the changes, but I can't roll back the updated material very easily. I'm hoping this works.

Various graphical improvements, fixed collider on small reactor.

Balance tweaks! If you see any balance problems, let me know!

Massive art improvements, largely due to TheEncircled.

Fixed medium reactor small port.

Changed textures a little so they're less goofy.

You may have to F11->reload textures.

Updated large reactor with the help of theencircled

Added category "XPAR" and added this stuff to "power"
