False tagging as illegal deck

[Lithimlin]

It may have to do with reprints or rotations, I am not sure, but in some cases decks are marked as illegal (in the following case according to the newest MWLs) although they are perfectly fine.
Here a Jinteki deck as an example. It is correctly recognized as legal by jinteki.net and will be marked as legal when copying the decklist and pasting it into a new deck.

It seems to be wrongly flagged inside the DB(Decks are only checked for legality based on quantity), I try to recreate the Deck at home later and look what happens when I simply copy your example deck and where the system gets hiccups. I checked the Card data and it seems its not based on wrongly set limits or restrictions.

do you have any reproduction steps? I tried to import that deck and saw some other wacky behavior, but it was listed as valid for a bunch of MWL formats, including the latest.

If you can narrow this down and tell us how you ended up in this state it will help us find a fix. Thanks for reporting the issue!

Unfortunately, the original deck is not mine, I just found it. So I can only assume what went wrong.
My guess is that the deck was originally fine (added on 2019-07-28) and the validity check somehow had an error when the new MWLs got added (since both 34 and 34b were released after 2019-07-28).
However, that does not explain why this is one of the few, if not the only deck with this problem.
