Issue description:

This is from a user in my discord his description of the crash: (On a server)
Just discovered an interaction between Powah energy cables and Pipez energy cable
A Pipez energy cable was connected to a Powah energy cable, and when going to configure it to break the cable, it instead tried to pull energy in a loop? and crashed the server.

Steps to reproduce:

(SETUP EXAMPLE & VIDEO BELOW)

1. Be on a server with only Pipez, Powah & Lollipop
2. Place down a Pipez Energy Pipes in a line.
3. Place down Powah Energy Cable ontop of the Pipez Energy Pipes.
4. Now place Energizing Rods ontop of the Powah Energy Cables.
5. Place a Powah Energy Cell connecting to the Pipez Energy Pipes.
6. Now configure the Pipez Energy Pipe that is connected right next to the Powah Energy Cell.
7. Put a Pipez Ultimate Pipe Upgrade into the pipe you configured right next to the Powah Energy Cell. (like this: https://i.imgur.com/UNx7hho.png)
8. Now sneak right-click the top Pipez Energy Pipes in the line with the Pipez wrench. (like that https://i.imgur.com/eDbSEuL.png)

More Info:

Had a conversation with HenkelMax the Author / Creator of the Pipez Mod on their issue tracker about this issue.
That issue can be found here: henkelmax/pipez#33 | It contains more info on this crash.

Hopefully I've included enough info.

Seems like both cables have no capacitance and instantly transfer from source to destination.
Both mods can fix this by having a network wide lock when simulating/actually transfering energy to prevent recursion.

Powah cables probably need a rework though due to the O(n^2) memory usage where n is the cables in a network.

... it's been a while; no response though?
