There's nothing at that location. I think it's a bug?

I cannot see your project. Please check that you have set it to public.

It is set to public. Maybe this link? [https://easyeda.com/renakunisaki/epaperteensymod](https://easyeda.com/renakunisaki/epaperteensymod) the board is "radio hat".

The first link does not open on a smartphone. The second is OK and the cause of the ratline is obvious when you zoom in: ![image.png](//image.easyeda.com/pullimage/SqDGfyhJbJZ7nzVOHRV2QEIYYDCn1bBMH7aV6CPA.png)

And when you check the Design Manager it is clear what has happened: ![image.png](//image.easyeda.com/pullimage/p9oG0kiav8aEXYnEXjFbIVfZGrQaxvlqAkYaRBSP.png) You have placed a via in a pad and then it has been moved by accident. Except for certainspecific cases of increasing electrical or thermal conductivity: **Do not put vias in pads!**

I see, thanks. Why not put vias in pads?

It creates a capillary action that sucks the solder away from the joint resulting in dry joints.

OK, I'll change the layout. Thanks!
