I am not able to explain why or how you was teleported to a way point as you should not have access to do so, but i can help get your items back. if you message me when your available i would be happy to help.
I do agree with the Factorio. i've been looking for an excuse to actually go back and play that game.
As for the race maps, i've not really played any of them. I'm open for most things you throw this way though.
