Went to go add another document to my University of Michigan application today, and all the sudden the fee waiver that had been there as recently as...I don't know, less than a month ago, was gone. Anyone else have this happen? Did it expire after a certain date? That'd really suck.

I had a slightly different situation. My code didn't work and I applied about a month after I received it..so maybe they expire idk. I just emailed them and they gave me a new one.
