I've switched to the newer version (v.5.4.9) and after than, the "Update PCB" function is automatically re-place the components on my PCB (I've nothing change on the schematics), and this cause missing contacts, not right placed components.
How can I solve this problem? !'ve attached before-after pictures, to show, how it's looks like after I updating my PCB.
Thanks for your help in advance.
