I've noticed a trend in one assembly in particular that when I create a component pattern, or in some cases, activate a configuration with a component pattern, that all of the instances in the pattern are suppressed. The pattern itself is resolved.
This happens as soon as the model is done rebuilding.
I can unsuppress the instances and it looks like it behaves normally thereafter.
I'm about to open an SPR on it, but going in, I was wondering if anyone else has seen this.
