I used seed -8850091472463892268 to setup this datapack. The bunker is centered on 0, 0 to make the writing of the functions easier and to make it easier to find your way home when you go exploring great distances away. I have written in a function that creates bonus chests inside the bunker that can be disabled in the file "init.mcfunction" in the directory data/bunker/functions. If you don't want the chests to spawn in with their loot, simply change the value on line 6 from 1 to 0.  If you want to change the appearance of the inside of the bunker, you can do so by editing the carpet, shell, stairs, beacon, and stations files in the directory data/bunker/functions/scripts. There is a lot of empty space in this bunker for you to build whatever you want. In order to use the auto sorter/smelter you must first set up the filters and signs by editing the filters and signs files respectfully in the data/bunker/functions/scripts folder but make sure of two things: 1) the item you place in the filter has a max stack count of 64 otherwise it will break the sorter and you'll have to re-run the init function to rebuild the bunker and 2) change the count value from 1 to 2. I also tweaked the furnace recipes to make them all cook in 5 ticks and added a recipe that turns rotten flesh into leather in a furnace. The auto smelter takes the smelted items and place them in the input feed of the auto sorter so when you add an item to the auto smelter filters be sure to add the smelted version to the auto sorter filters otherwise they will be placed in the "everything else" chest. There is plenty of room to add what ever items you want to automatically smelt and sort to the system. The sorter can hold up to 14,784 of each item it sorts out.
