there is no such thing as a legacy maproom (well there shouldn’t be) , as far as I remember when the build changes everything that is now built via hammer and was in chests is broken down into resource packs

90k stones is 900 stacks , which is technically possible because each bench automatically increases its inventory when it needs to , you just can’t add anything until you take the excess…

900 stacks won’t fit in your inventory by the way, that’s also limited as far as I know
