Hello there!
I am missing the difference between the protect items and the other one, for example the "protect hobo barrel" and the "hobo barrel".

Also, after reading all the other messages, it is not perfectly clear to me another thing: when there is this flag set:

  "Hats do not use fuel (true/false)": true,​

 And the device is set like that:

  "Fog Machines (true/false)": true,

Does the fog machine (for istance) consume fuel? Because that is my configuration but the fog machines still consume low grade fuel.
While the snow machine works without any fuel

  "SnowMachines (true/false)": true,

Thanks in advance! :-D

Protection basically is for ovens (things that cook or process things) it means they do not get altered to just looking on if they are really on so that we don't interrupt processing.  For things that are just doing things (producing light, fog, snow)   altering their states doesn't mess up any processing so they do not need protecting.

for Hats and devices, True = yes please do this, False = I want this to have normal vanilla game behaviour.

Hat do not use fuel allows you to add 1 fuel to a hat, turn it on and have it never run out of fuel.  It does require at least one seed fuel.  This is to avoid an exploit of toggling it on to get a free fuel, which players did when it needed no fuel at all.  It just replaces a fuel as it is burned so its fuel level stays stable.

Fog Machine and Snow Machine basically allow them to run continously with no fuel producing fog or snow.

Did that answer your questions?

Yes, you answered all my questions and thanks a lot! :-)
