Open the extractions with the cart. Idea is not mine, just keeping the mod up. I can't remember credits. Are you the creator of the mod, and want credited? Reach out to me on discord, napp1101.

Works in both singleplayer, have not tested in multiplayer.
Install via Thunderstore Mod Manager, or drop the DLL into your BepInEx/plugins folder.
