I’ve had completed series where multi episode files (isos in my case) were deleted while only ONE episode is fetched in higher quality, hence uncompleting the series.
Kind of a major issue imho.
Its an issue, but I wouldn’t call it major due to the limited number of double episodes (compared to single eps).

Its worth setting up the Recycling Bin feature in Sonarr to catch these issues though.
A little more detail.
I’ve had multi-episode isos in the following style.
series_name.S05E01-02-03-04.720p.dvd9.iso
… which are nicely recognized by Sonarr.
I’ve set the series to grabbing of 1080p versions, which he does.
Now, when for instance S05E01.1080p is found, downloaded and auto-moved to the series folder, the iso file gets deleted.
Hence E02-03-04 become missing.
Secondary issue. When I readd the iso, the E02-03-04 does not get picked up by Sonarr as present.
Only when I rename the iso to series_name.S05E02-03-04 … (so omitting the S01) the files get found.
