Hi,
if you need you can add a new rule for the MagnetCrane in the junkyard.

add in config RuleSets -> rules

"magnetcrane cannot hurt players"

and add the new "magnetcrane" entity group:

{
      "name": "magnetcrane",
      "members": "magnetcrane.entity",
      "exclusions": ""
    }

This will prevent the magnetic field from killing players when you hit them with it^^

can you post your config? I am trying to see why this would be needed as it should be blocked by default

sure, thanks for your help :)
