I'm working on a project that consists of many subassemblies. As I complete each subassembly, it is fully mated and resolved without errors. I also have the subassembly mated and without errors in the higher-level assembly. When I close SW and reopen it, usually the next day, everything blows up because all of the mates are suppressed. I haven't changed configurations, so I know that's not the problem.
What's going on? Have you guys seen this before?
