Mirrored Component References

We recently came a cross a problem with mirrored componentsand it's happened a couple of time already.

While working on an assembly with mirrored components all of asudden (not triggered by any action in particular) a Mirrored Partis asking for the Plane that was used when created. This doesn'tmake any sence because it is currently opened.

There's no way of fixing this because there is no history (Feature)of the Mirrored Component on the Design Tree.

I did some testing and found that whenever Mirrored Component iscreated if you go to List References, the References for the PlaneUsed to create that part is Out-of-Context, even if that assemblyis opened in SolidWorks, and there's no way of re-referencing tothat plane.

Am I missing something? or is this just how mirrored componentsbehave?SolidworksAssemblies
