Odd Subscription File showing up

For some reason a doy 280 file showed up in several of my subscriptions and was downloaded.
It could not get past modis_L1A.py . From:
LogStatus.MOD00.A2020280.0330.MRIVER_FULL.L1A_LAC

I have downloaded the file twice and it is small. Much smaller than the previous MOD00.A2020280.0325_1.PDS.bz2

Terra experienced an anomaly on DOY 279 and into early 280, so there are missing data:

DOY 279
15:04:02 - 15:08:36
16:47:03 - 16:51:37
18:30:02 - 18:34:36
20:13:01 - 20:17:34
21:56:00 - 22:00:33
23:38:59 - 00:31:41

DOY 280
01:24:21 - 01:33:51
01:37:42 - 01:52:57
03:20:20 - 03:41:45

Unless these data are recovered from direct broadcasting stations, there will be a gap. The NRT files near the anomaly may have issues, refined files will probably be cleaner (and yes, smaller- unless subsequently reprocessed if the DB data come to the rescue).
