I'm playing on a server <-> client env. and trying to get damage from uninsulated cables.

For testing I put down 2 MFSUs and connected them with uninsulated HV wires. Standing next to them did transfer all the power but I did not take any damage from it. Config file on client and server are the same with:

# Damage entities on contact with uninsulated cables
B:"Uninsulated Electrocution Damage"=true

# Spawn particles on contact with uninsulated cables
B:"Uninsulated Electrocution Particle"=true

# Play sound on contact with uninsulated cables
B:"Uninsulated Electrocution Sound"=true
