I have added a link to a Bug Report / workaround here: [https://easyeda.com/forum/topic/How-to-solve-PCB-components-removed-and-added-after-Import-Changes-or-Update-PCB-9dbbeabbfdfa401986fa1d03b2316245](https://easyeda.com/forum/topic/How-to-solve-PCB-components-removed-and-added-after-Import-Changes-or-Update-PCB-9dbbeabbfdfa401986fa1d03b2316245)

Hi Andy, thanks for you workaround. I cant tell how easy it is, because without trying it out, I cant intuitively gauge how it involved it. It reads still quite cumbersome. Right now, I've helped myself in the following way: I have several equidistant modules in a line. I fix the placing for the first and last module (using a couple of vias as alignment marks, and then moving in the entire bunch). Next for the intermediate modules I use the distribute vertically and align left functions, to drag the components in place. So I hope the announced fix will cover this here issue as well.

@tobalt, I haven't tested it with modules but I think that once they are placed in a PCB the issue and the workarounds should be the same.
