I have 2 assemblies that are similar (one larger "heavy duty" size, one smaller size), with similar component and subassembly names, but they are in completely different file locations. I have edited the references in the assemblies several times, but if I open both assemblies at the same time (for purposes of comparison), whichever one opens second loses its references to 2 particular components and they disappear from the assembly. It doesn't matter which one opens 1st - the 2nd one to open loses its references. And again, the referred components are completely different unshared models in different file locations - only with similar names.
If I open the assemblies separately, all is well.
Seems glitchy. Should not be a need to rename files, right? File paths are miles apart.
Not even sure what I'm asking for here as far as a resolution. It's just weird.
