Okay, I found another instance in my logs. Looks like this is the culprit:

Looking at
http://www.thetvdb.com/api/GetSeries.php?seriesname=Ink%20Master&language=all it seems to me the proper series id is 254986 but then MC looks for 4867663 which doesn't exist, so it fails out. Looking at the file, MC has [TheTVDB Series ID] as 4867663, but I'm not sure when/where that's getting set.
The first instance of 4867663 in the log is it looking for cover art:

Looking at previous episodes in the series, they all have 4867663 set for [TheTVDB Series ID], but all but the most recent 4 have the correct name, etc. Thinking about it, the failures to lookup started after my switch to MC20. Would that have corrupted that field somehow?
Going through some other shows having the same issue but that don't show in the log I have I see that there are some issues with pulling the wrong ID based on name "Once Upon a Time" vs "Once Upon a Time (2011)". Once Upon a Time (2011)/Season 04/Once.Upon.a.Time.2011.S04E03.SD.TV-LOL.mp4 is being pulled in as the former and thus getting a 404 because that show only has one season while the latter is the current one. [Date] is getting set as 2011 but [TheTVDB Series ID] is 83822.
I guess unless I hear differently from you shortly, I'll go through and sanitize all the [TheTVDB Series ID] fields to be valid and then see if going forward it keeps with that or continues to generate spurious ones.
