Hi, i am working on a big project. where i need to duplicate 16 times the same circuit into one big circuit. in order to do that i created a schematic module and pcb module corresponds to a single circuit. i place each pcb and then placed the suitable schematic module and since it had the same indexes it connected it properly. at certaing point i modified the pcb module, and from that point when i place module on schematic and on pcb and then i do update pcb it is create some irrelevant components and does not create connection as in the schematic. does anyone knows what to do?
