Additional information:
This has been happening for about a month now and it keeps happening when trying to post-process any episode from two anime series, Dragon Ball Super and One Piece. I didn't test it with any other anime series.

Post-processing for all other (non-anime) series works just fine.

Does anybody have some more info on this as to what might be causing this error?

I'm still getting this error message, so anime post-processing is still broken to me.

What is your custom anime naming pattern?

[noodle-]

I've set it to custom: %S.N.%0E.%SQ.N.%RT.%RG

Oh, but I just noticed the non-custom option Show.Name.003.Ep.Nameworks!

Rambling/debugging below this point.

%S.N.S%0SE%0E. produces Show.Name.003.ext. This is what I want, but I have no idea why there's S%0S for season number in there, or why there's two zeroes, or why the S and E don't show up in the result. Maybe I'm misreading the naming legend..?

So I remove the season part

%S.N.E%0E Doesn't work

@noodle-

%S.N.S%0SE%0E. produces Show.Name.003.ext. This is what I want, but I have no idea why there's S%0S for season number in there, or why there's two zeroes, or why the S and E don't show up in the result. Maybe I'm misreading the naming legend..?

I don't use the anime feature at all, but I know you have an option below to choose the episode numbering type:

• Add Absolute Number
  Add the absolute number to the season/episode format?
  Only applies to animes. (eg. S15E45 - 310 vs S15E45)
• Only Absolute Number
  Replace season/episode format with absolute number
  Only applies to animes.
• No Absolute Number
  Don't include the absolute number
  Only applies to animes.

I've set it to custom: %S.N.%0E.%SQ.N.%RT.%RG
%S.N.E%0E Doesn't work

I can get the error with the following configurations:

• Pattern [Custom]: %S.N.%0E.%SQ.N.%RT.%RG
  Episode Numbering: Only Absolute Number
• Pattern [Custom]: %S.N.E%0E
  Episode Numbering: Only Absolute Number

So the bug is related to the "Only Absolute Number" option.
I'll try to find out what the issue is, but I don't know anything about that part of the code,
so no promises :wink:

Fixed in develop.

Thanks for all the information, and for fixing the issue of course! :heart:
