ooh, I think you nailed it. One of the reasons I was taking the top 10
out of the cycle was because I wanted to fill in some holes where tapes
had gotten damaged and because I had 6 sets of 15 and 1 set of 10 tapes.
Unfortunately, I had not yet added those tapes in so I had a tape cycle
of 90 and only 87 tapes in the tape list.
Running it now to see if that works. If so, I will add a couple more
tapes at the top of the list again to prevent this in the future.
Thanks!
