The "board" tab looks incorrect, will my boards be manufactured correctly?
How to deal with board viewer issues/bugs
Occasionally the board tab can have rendering bugs. If something looks incorrect in the rendering we recommend looking at the Gerbers we generated (they can be downloaded via the "Download assets" button at the top right of the projects page). So long as these Gerbers look correct you should be good to go, as these will be the exact files used for manufacturing.
