My cousin was on her reunion planning committe and she said it was a ton of work just trying to find out where people moved to, if they'd died, etc. This was 20 years ago, so it was pretty much all phone calls and mailing letters, but I'd imagine it's still a good amount of work to get contact info.
To me, that would fall under the "didn't know when it was going to be until it happened." I picture not being invited as meaning they didn't want you to come/you weren't allowed to come, which is why I was baffled that could even happen. Not being able to contact you is a different scenario.
