I noticed a bug with inserters and a wagon near a bent rail. Hard to explain. Please see attached savegame, its the inserter that is 3rd from the bottom(it is hard to miss the stretch)

I am not sure how long the bug has been like this, noticed it personally the first time in 0.10.2, but my guess it has been like this for a while and not been noticed

Thanks for the hours of fun with the game!
