I followed the stack trace and found the issue starts in HWYLA>mcp>mobius>waila>addons>capability>HUDHandlerEnergy.java In getNBTData, it calls getCapability on an instance of TileBaseUniversalConductor (TileEntity player is looking at, in my case Sealed Aluminum Wire) and passes in a null EnumFacing object as the second parameter. In getCapability, getTileEntityOnSide is called on a new BlockVec3 object and the EnumFacing object is passed in again. In getTileEntityOnSide, ordinal() is called on the EnumFacing object, causing a NullPointerException. This happens on every tick the player is looking at the block, causing the server to hang and crash.
Edit: I found that this only happens while EnderIO is installed, since if it isn't installed, getCapability just returns immediately.
(I did see contributing rule #5 but the HWYLA page doesn't allow issue posts)
