illustrator won't make diagonal lined seamles pattern
Dear Illustrator community!
I have a problem, Illustrator won't let me make a seamless diagonal lined pattern (see image attached).
I rotated the lines at 45 degrees, but they won't matchup with the repetition. I even tried to manually tweaked it but the lines just jump away and don't want to be connected properly (see photo). I'm also adding a photo of my settings. Curiously horizontal and vertical lines are fine. Any ideas what I might be doing wrong?
Thanks so much for you help in advance!
