Sorry, I'm really new and do not know how to word this very well. Somehow during this I grabbed and moved this vertex without realizing and now I am too far in to undo it. I need to find a way to get it back to its original spot in the loop without moving any of the others around it. I tried hitting W and messing with a few of the tools but I haven't found one that works yet. Hopefully there is a quick fix for this. Thank you in advance.
If its only moved on the y-axis... you could press "n" to get the properties window on the right side... and copy the y-position of another vertice in the ring to that vertice.
