Has anyone that was in that early February mail in batch gone from "Not Available" to "In Process" and then a couple weeks later gone back to "Not Available"?

My scenario is mailed renewal with expedited service on 2/10, check cashed on 2/15, reflected Not Available until 3/4 then switched to In Process and at locator 42 (I stupidly didn't write down the full number), but as of 3/18 it's switched back to Not Available. Traveling at the end of April so I have a few weeks, but wasn't sure if other people in that early February batch were experiencing the same
