On a multiplayer (or single player) world, when you get the slime lantern and don't analyze it, you're unable to forever. There's no way to get another rotten slime lantern nor analyze the used one. It's worse when you play with others as they could use the lantern and not analyze it. Maybe be able to craft them? Or put more in the world? maybe be able to buy them for raw science?  Help the completionists please!

Only modded would do this there isn't much of a reason to add more junk to the game. If you're a collector and want the raw science keep that in mind next time.
