Hello, I got a big issue on my current project today, It's a shared project, my partner and I dont see the exact same project, the ground plane is not sync. When rebuild ground plane, the PCB tab is not marked as "*" (need to save). Also DRC dont catch the bridge and my real PCB goes to trash :( **What my partner see :** ![Image1.png](//image.easyeda.com/pullimage/91JUDj6KqmFEAu10kOwKWu3tNKDv2lZlwxetBKrk.png) ## What I see ![Image2.png](//image.easyeda.com/pullimage/Gz8VDo0WwOvuidUlrJ0m4URRnERjHKxQ5wxNqjCF.png) As you see U7\_7 is short circuit to ground plane\. I dont know why project is not sync only on ground plane\.\.\.I dont know why DRC dont catch this \(Gound plane NET is GND\, whyt DRC let connect to U7\_7\)\.\.\. I always check my file before production, I always rebuild ground plane before production and I always check DRC before production, I dont understand how this can append. The desync disturbing me This scarry me !
