I dont really have any other info to provide. It was going along and spit this out in the same spot each time. I dont know what torrent it was on because I think it only shows the name after it's been processed

[newadventure079]

It might be due to add_limit_percent = 100. I had it at 100 and it happened each time. I changed it to 99 and it didn't error

[JohnDoee]

It probably thinks there's a match when all files are missing, since that's what add_limit_percent = 100 so should be easy to fix.

I'm using add_limit_percent = 10

[newadventure079]

I'm seeing this again and again now

[newadventure079]

I debugged this and found the issue.

In _select_best_candidate(), evaluated_candidates is an empty list, so the call to sorted()[0] at the end of the function causes the list index out of range error.

I actually had a folder that contained video files and also a DVD VIDEO_TS folder. I think at2 was trying to add all the individual .VOB files and such. I told at2 not to match DVD folders and now it works, but a check for an empty evaluated_candidates list should be added to the code

[newadventure079]

I didn't like how it would mark DVD torrents as Failed because I had .VOB and .IFO as an ignore_file_pattern. So what I did now was before we call self._select_best_candidate() in match_files_dynamic(), I put in

if len(candidates) == 0:
    return DynamicMatchResult(False, current_missing_size, None, None)
