If you have any testing worlds, please go to your world folder and delete the power_systems directory. All of the wires in your world will be deleted with it, unfortunately.
Fixes and improvements
Wires now properly render interdimensionally
Now wires drop if you overextend it when trying to connect wire posts, when you break wire posts, and when you cut them with pliers
Grids now don't break when a part of one is in an unloaded chunk. The remainder of the grid freezes until all of the connected appliances are loaded again
Fixed Heaters not seeing already existing blocks when placed
