I built something. Don't ask why, because you don't want to know.
One thing I need to verify is that the redstone and ... fissile material... doesn't overload other people's clients.
Please go to "/warp reactor" and let me know if your client slows down too much, and at what point in the building that happens. Some lag is expected, but I need to see if it's minor or if it makes your client seize up and scream in tongues.
If going there immediately lags, or if you're feeling cautious, try /warp reactor_safe, which puts you a little further away.
