There is a level from mobius currently not loading correctly causing an error due to a tileset error: - "Slaughterhouse" (Autumn 2016 LD Contest Winner, NeoLemmix)
This error needs to be fixed by mobius if he wants to make his level accessible.
Here is the error version of the level + tileset anyway (https://www.dropbox.com/s/ahdjx3qm6kt03on/m%C3%B6bius%20slaughterhouse.zip?dl=1)
Very sorry but I have no time or inclination to fix this error. Unless someone else wants to do it I suggest just removing the level from the contest.
I'm honestly not proud or excited about that level, I forced myself to make that level when I had no inspiration and had no solution in mind and it ended up with many solutions, none which I was particularly happy with. I don't even like the appearance or layout or play-ability of it. This tileset was also released unofficially and that wasn't a good idea either.
