I have been stuck on this particular level for weeks now and it's driving me mad. I finally resorted to trying various solvers and none of them managed to find a solution. Is this level really impossible to solve or can it be completed? I hope someone can help. Just letting me know there is a solution would be fine, and a solution even better.
I've attempted to paste one of the positions I'm trying to solve from but I am not positive I didn't make any mistakes on the edit so Im not sure how much help this will be.
Thanks in advance.
Edit: I just realised that Howards fourth set #13 and Original #50 are slightly different. I have since solved the original #50, so my question only applies to #13 of Howard's fourth set. Hope this is clear.
