The most unhinged ways to transport items and yourself around your factory. Fling items around with Thrower Inserters, launch your trains off ramps, and soar through your base on electric ziplines!
I noticed this when trying to void iron plates in version 2.2.13. Whenever you try to recycle a chest, it instead returns the open container item. This overrides the vanilla behaviour of returning iron plates. Likely because this is a deepcopy of the Iron chest, it has auto_recycle=true, even though putting the lid back on is an alternate recipe.
