Things inside vault not spoiling at all due to Performance point and being hidden deep from surface heat.


Addition of any auto retrieval from Vault will or taking items when pawn trying to craft/build something will ruin Performance point. Overall Underground Vault was intended to be additional player controlled tool, rather than replacement for existing vanilla storage system.
But there is a Storage Vault Shelf, that will automatically store items in vault, if amount of stacks on it exceed threshold, and will take items from vault, if amount of stacks on it below threshold.


Performance is the main consideration of this mod. This mod was made for countering late game Things piling up on base map and making each pawn running through every single Thing on a map for job creation. Due to that Things in Vault not taken into consideration by game as being on map, so not counts towards Wealth and even not really Tick.

For the reference: 1 Vault with Terminal affect perfomance as much as 1 Shelf or 1 Camp Fire, but allows to store nearly infinite amount of things inside Vault. Additionally due to the fact that all things inside Vault not counted as items on the map then each pawn job or game action that search for item will ignore them.

Example: You have 100 stacks of wood. In vanilla shelf or modded storage it will take less space, but each job of each pawn will run through each of 100 stacks of wood. Which affect perfomance quite badly, when you have a lot of things on your map. But if you put 90 stacks of this wood into underground vault, that game each job of each pawn will see and run through only 10 left stacks each time. Thus decreasing amount of stacks game constantly checking through by 90% in curren example. And if you do run out of wood on surface, then you can just select to retrieve some of stored wood from vault.


You can install it on a Gravship and use it like you normally do. While it intended as Vault is located deep underground, for Gravship Vault can be considered as a cargo bay located at the belly of the Gravship.


There is some ways how Underground Vault can be abused as you can guess by Performance point. But it up to a player to decide how to use this Tool to their advantage and whenever to cheat with it, use normally or consider it as lesser evil for better performancein big colony.
