[1.11.2] Rf tools disappearing

[dwilby]

Every time I spawn in my rf tools they immediately disappear. There is no error message and I am able to spawn in tools if I change the max rf to small numbers, however if I go over 64000 rf, they disappear immediately. I have traced the reason for it to disappear to its updating in the on update method here. I don't know why it happens or how to fix it.

The onUpdate method sets the energy level equal to the damage
