[1.18] ComputerCraft Computer crashes after a while when reading values from Energy Core #1737

Base information

Description / steps to reproduce

An error occurs when trying to get the energy readout on a ComputerCraft computer for an Energy Core either after a while or after the chunk unloads; unsure of what the trigger is, but it happens very often when joined to a dedicated server.

Relevent error:

java.lang.NullPointerException: Cannot read field "energy" because the return value of "com.brandon3055.draconicevolution.blocks.tileentity.TileEnergyPylon.getCore()" is null
