any chance you could just block the tunnel from been moved with picker dollies instead of making it a conflict?

I didn't know it was possible to stop dollies from being able to affect a list of names entities?

In the old days I didn't think it was so I just added the conflict to this mod when I started it ages back.

In addition a remote api to disallow moving of an entity is available:

if remote.interfaces["PickerDollies"] and remote.interfaces["PickerDollies"]["add_blacklist_name"] then
remote.call("PickerDollies", "add_blacklist_name", "name-of-your-entity")
end
