Is there anyone out there who ignored last year's Army IRR muster, if so, what were the repercussions?

My questions are very specific. 1) Is there anyone out there who attended last year's muster and has since been activated? 2) Is there anyone out there who ignored last year's muster? 3) If you did ignore it, what happened? Were you clified as an unsatisfactory participant, processed for discharge, or nothing?
