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 think this is a new bug as of 2.1.12 since my base broke; thrower inserters sometimes won't throw fuel into furnaces with hatches when overflow protection is enabled. In my testing it seems to fuel furnaces correctly when first placed, but then won't refuel furnaces after the fuel is burned up or manually removed.
