Internal Server Error: /api/release

I’m having a problem downloading just one specific episode when I manually search, and it’s from the “Specials” season. The exception looks to be:

Empty collection is not allowed.
Parameter name: remoteEpisode.Episodes
at NzbDrone.Common.EnsureThat.EnsureCollectionExtensions.HasItems<NzbDrone.Core.Tv.Episode>

Here’s the trace log:

(I also don’t understand why it’s giving me “Size: 1920839403 is greater than maximum allowed size (0), rejecting” since there is a min and max size set and it should be within the limits. I tried moving the sliders and resaving and that didn’t help)

Exact same issue: Cannot manually download some specials
