I noticed that a lot posters for Supernatural were deleted on the thetvdb because the were duplicates. As I didn't want to download and repleace them directly I simply deleted all but a few and run Import expecting tvseries to download the missing artwork. Well, it didn't happen. I think that's how it worked in the past, instead all reference to the missing artwork were deleted. So even downloading them directly and running import again, tvseries does not recognize them.
My download limit for banners is a lot higher than the amount of posters for that series. So, what can I do?
