**BUG** Hi Dillon, I don't think this is a bug. I think it is something I have forgotten or done wrong. Can you tell me what is my mistake? :) * Here is my problem: When I first passed Tesseract into PCB it did not have any of the 4 off 3.5mm mounting holes in the PCB. I added 4 off 3.5mm holes to the PCB but then realised that every time I did **Import changes**, the holes were deleted because they were not in the schematic. So I created the symbol named `unplated_M3_clearance_hole` with a prefix of `3M5_H?` and added 4 of them to the schematic and assigned them the footprint `hole_3mm5`. That fixed the problem with **Import changes**. But now there is a problem that when I try to generate a new PCB from the schematic, I get this error: ![Footprint error message][1] Steps to reproduce bug: 1. Create a schematic 2. Place `unplated_M3_clearance_hole` 3. Convert to PCB... Results: Get the error message. [1]: /editor/20150725/55b2b0eb49b41.png
