MM8Patch v2.5.4

[-] Now, when a location re-spawns, all artifacts generated in chests you've never opened get cleared from "obtained artifacts" list.
[-] My bug: FixMonstersBlockingShots option didn't work right.
[-] Prison of the Lord of Water (d38): An artifact was being generated in an inaccessible chest, leading to it not being obtainable by the party anymore.
