I'm working on a board, but one of the pins keeps getting connected to ground even though it is not in the GND net.
It displays correctly in the EasyEDA design screen:
The image shows the top two pins (correctly) disconnected from the rest of the bottom layer ground plane.
But if I use the Gerber viewer to view the board I get the following image:
Notice that the top right (top left from the front) pin hole appears to be connected to the bottom layer ground plane.
What's more, look what happens when I try to work around this by drawing the bottom copper area around the problem pin.
Notice how the problem jumps over to the next pin that still remains inside the copper area?
I think there must be some problem with the way that the pcb design software is outputting gerber files.
Perhaps it is forgetting to properly close a shape when drawing on the copper voids in the area?
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
I found another instance of this bug on the front of the board.
The highlighted pin hole should have 4 spoke connections to the copper layer around it.
But when rendered by the gerber viewer we see that one of the gaps between the spokes has disappeared just like the gap surrounding the pin pad in the last set of images.
Hopefully this information helps someone find the bug.
