Hi, I'm just reporting a copy-&-paste bug:

water-mining.lua, line 515:

},
circuit_wire_connection_points = circuit_connector_definitions["pumpjack"].points,
circuit_connector_sprites = circuit_connector_definitions["pumpjack"].sprites,
circuit_wire_max_distance = 17.5,

should be:

circuit_wire_connection_points = circuit_connector_definitions["pumpjack"].points,
circuit_connector_sprites = circuit_connector_definitions["pumpjack"].sprites,
circuit_wire_max_distance = 17.5,

},

Best Regards

Right, I'll make a note of it.
