Polygon errors on board maker website

[alex-x-taylor]

I attempted to upload the .brd files to get some boards made (oshpark) and got an error code. After reaching out to support and submitting a file to them they say that there are some polygons with mismatch ends. An example they gave was instead of a corner coming to a nice 90 degree point, it overlaps and turns into a small bow tie. I'm planning on combing through the board designs and looking for any wayward polygons.

Thanks for your hard work!
