[1.12.2] Ticking Tile Entity - "other" properties

[stepsword]

Hi,

 

I couldn't find a definitive answer on this, but does every single class property have to be saved to NBT on a Tile Entity?

 

For example, I'm overriding the update() function, and doing something server side only. Does the counter I have which counts ticks need to be saved as a property in read/writeNBT? If I don't save it will it just reset at world load? Also, is it necessary to notify the client if that property changes assuming I only use the property server side?
