v0.8.2: Fixed the following bugs:

- ring of energy not increasing ghost HP regen
- magical charge buff not increasing the range on disintegration
- remains in pit rooms rarely containing a cursed item but not being haunted
- wandmaker rarely spawning ontop of traps
- rare crash bugs when windows are saved as a scene is being cleared
