TileEntity throwing exception trying to write state it will not persist

[camdent8]

Issue description: No idea what exactly is happening as I cannot load into my server but last night was playing an ATM6 server building something for a new mod I was doing and the server crashed completely out of no where. I tried joining back but it crashed 3 times and I went to bed. I woke up and was able to get on normally but there was one single chunk unloaded that wouldn't load no matter what I did, I assumed it was client side so I left and joined again and was unable now my console is flooded at all times with:

[Server thread/ERROR]: A TileEntity type mcjty.rftoolsbuilder.modules.shield.blocks.ShieldingTileEntity has thrown an exception trying to write state. It will not persist, Report this to the mod author
java.lang.NullPointerException: null

I do actively use Shield Projectors for multiple things like housing my bees and a few hidden walls for ease of access but they had been fine until the random crash last night.

Steps to reproduce: Literally no idea and cannot try to reproduce as I can no longer join
