I have an invisible vertex or something wierd and I dont know what it is.
I added an image of what happened:

One arrow shows a bend where there is no vertex - How? The other points to a darker color around a vertex, which reminded me of normals but I dont realy know what it is..?
Anyone knows what this is and how to fix it?
Thank you!
