Another new one today..
I was #1 on the WL since it was viewable at T-72 hours for J=4. At some point within T-36 hours, the WL began erratically displaying results. The pax position and # of pax would shift around change upon every few refreshes of the WL. The UG processor appears to have ran around T-23 and J=0, and then the WL resumed displaying the original (correct) order.
So, that's cool. 👎🏻
