Note that this patch is available in the beta branch (you can select it from game properties on Steam) until I've confirmed the changes aren't game breaking in any way. This patch will change random generation such that loading a save from a previous version will result in items, enemies and other RNG elements to not be what they were before. Once this update is on the main branch, I will make the previous patch available on a separate branch for save compatibility.
