Requires Pal Schema (Sorry for the external dependency, Okaetsu has not posted Pal Schema to Curse Forge)
I do not intend to respond to posts or "bug reports" here. If you have questions or issues please post them to this mirror on Nexus, I'm quite active there.
You can edit the CustomContainerSlots.jsonc file in this mod with any text editor to give any container in the game a custom number of slots.
I made this because I don't like x10 or x2 or xN mods. I feel like some containers shouldn't be changed, some should be x2, and others should be +5 or whatever. I wanted to pick the numbers myself, so now you can too.
Only change the numbers. Don't change anything else.
Note: Just like every other storage slot mod out there, this cannot change the size of storage containers that have already been built, and containers that were built with this mod will keep their slot change after uninstalling. You'll have to destroy and rebuild all of your containers to get your new slot count. In order to rebuild the guild chest, you must join a newly created guild. If joining a new guild isn't possible because you play single-player, you'll have to start a new game or edit your save using a guide like this (Sorry for the external link again Curse Forge doesn't have what I'm looking for)
