Hello. The problem is that VC replaces some components with some other component by itself. This can not be noticed when doing the layout but when I open the layout again, some parts may be replaced. Is this known behaviour? At least it is very annoying as it can replace components from huge assembly and replacing them is very time intensive. Basically when this replacing happens, I have to get a backup file that is not broken.
In the attached picture this has happened, some components that were on the table has been replaced with robot pendants. The layout was okay when I closed it, but was broken when I reopened it.
