Help with glitch! – SpriteBox : Code Hour Review

Half way through level 3 (desert level) there is an extra box that blocks your path and no sprite box. I saw another commenter from a month ago is having the exact same problem as me. Will the developer please fix this or tell me how to? I’ve watched a dozen play through videos of this level on the web so it is clear that there is a an extra brown box that is blocking the path. It seems one of the recent updates created this glitch as it was not a problem in any of the earlier reviews or YouTube video play throughs.
