I have No Decay set up and working with my permissions. Trouble is, windows and doors in particular (also hatches and other placeables you craft into inventory and then place) are still decaying. Is there any way to get the No Decay settings to apply to those crafted entities?

Add the desired entity in the other multiplier section of the config file
"Other multipliers": {
"furnace": 0.0,
"minicopter.entity": 0.0
},

Ah ok, thanks for that! Would maybe be helpful to folks if the default configuration included the entries for all the entities that would normally be part of a base, since one of the mod's features is to prevent players from putting resources into a TC. Just a suggestion, thanks for the info!
