A friend of mine is wondering if, when he switches maps, if there is a way to preserve the alchemical bag's inventory.
I would assume that, since their inventories are independant of the level.dat of the map, that even though their inventories and such would be reset, all you would have to do is back up those 'independant' inventories, make the new map, and then cheat in or make another alchemical bag of the proper color and you'd be good-to-go. This is all conjecture mind you, so it would be helpful if you could confirm or deny my hypothesis.
