i have a few energy storage blocks receiving and sending in my base, they are connected trough an energy pylon line to a substation 2km away where there is another energy storage block receiving and sending energy and theres also another place 2km further that is also connected to the substation in the middle and there are energy storage blocks in there as well which also receive and send. all energy from all the energy storage blocks disappears.

I had this issue and discovered that it appears to be a fault in the energy converter; apparently, you can draw power from it infinitely when the battery is below the conversion for 1 RF or something

This issue might be patched as of recent; Try this again to confirm if this issue is still fixed or not

Try adding chunkloaders where the batteries are.

also may be worth mentioning the other place that is 2km further away was loaded when this problem arose because its a lan multiplayer
