I think it has to do with a procedure called Y=50 but I can't understand the problem with it, if anyone can help me it would honestly get awsome!!

Thanks Klemen!! 

I just want say, and I think I speak for most, if not all of the MCreator community, that we really appreciate all the work you've done this past few years, and even though you might be leaving development for a while, the thing you created will continue existing and improving!

Thanks!
