Say you're playing alone, the game doesn't compensate for you being alone by lowering requirements of said puzzle with having to find equipment all over the map, nooooo.
Instead, welcome ES to allow you to play the actual game more than having to go up to FOUR max to get a stupid equipment item to progress the map.
From a small amount of testing, this is a full-on client side mod, player hosts won't be able to change it for you.
Honestly perfect if you're playing alone or with two people, otherwise you won't really need it.
Big ass note: this doesn't allow you to carry more bags, only equipment items.
