Issue description: The RF Tools builder causes extreme CPU usage (i7 maxes out at 100%) and takes an extremely long time to process a single tick. Causing other blocks and mobs to slow down dramatically. If left on for too long the server also crashes due to a single tick taking 60 seconds.

We have tried a clearing quarry card and a non-clearing quarry card (replaces with dirt) with the same problem. Even a small 1 - 2 chunk area is causing the very long tick times. The shape card and builder had been replaced twice, with the issue being repeatable each time.

I have also attached two screenshots showing the high tick time.

Trying a single player world also reproduced the same results.

Steps to reproduce:

1. Place down a builder
2. Measure out a quarry shape card
3. Insert it into the builder and turn on the builder
4. The land is quarried but CPU usage is very high and the builder block takes a long time to process a single tick.
