I am on the track puzzle right now, I have found the spare track piece and I had activated the lantern on the bottom and the bottom right, but the one on the very right does not have a possible path for the minecart to go to. I have tried placing it in the top path and activating the switch again, but it just disables when ever you click it after restarting the puzzle. with no possible track the leads to it, in any position on the first try, I cannot progress.
Hello. There is a way, it's just the sprite of the rail being a bit awkward. But technicaly, the minecart can move like this and the Right Lantern shall be lit on. Sorry for the confusion and I hope it will help!
