Hello there,

I'm trying to build a modern deck but it seems deckbox has a small bug in showing the right format of the deck.

This deck is shown as complete, but isn't labeled as modern anymore as soon as i add some basic land cards:
https://deckbox.org/sets/731870

it also doesn't show up in deck database when i filter for modern and search for the name of the deck.

I think if any of the cards you used are in the M15 Core Set then it won't show the format until that set is out officially. I've no idea why but I've noticed that before from previous sets. Switch to spoiler view and you'll see that you have a few cards being reprinted in M15.

Hmm.. nopes, that's not it.

Here's the deck without land and it contains several M15 cards and it is labeled as modern:
https://deckbox.org/sets/732680

Only as soon as I add the lands the modern label vanishes.

Edit: And the issue is only with basic lands. Non-basic lands work fine as you can see in the incomplete deck above.

Well that's kooky, same on mine as well. I've got 3 or 4 decks, all Modern, that don't show the format either. Take the basics away, format shows up. Standard and Legacy decks are fine though. Weird.

Standards don't work for me either.

A standard deck with basic lands and no standard label:
https://deckbox.org/sets/731996

Same deck without basic lands and with standard label:
https://deckbox.org/sets/732708

Thanks for reporting, fixed now. Some decks will still not show correct legality yet, that info is refreshing currently. If you add cards to decks though, things behave normally again.

If i understand that right, adding a basic land to the two correct labeled but incomplete decks will still show the right label now?

That's not the case for me.
Added a Swamp and a Mountain to both of the test decks above:
https://deckbox.org/sets/732680 - modern label vanished
https://deckbox.org/sets/732708 - standard label vanished

Edit: by the way.. is there any easy way to clone a deck?

Yep, posted too soon, server was not restarted yet :D. Works now though.

@ copying, yes, Tools -> Copy (Top right menu).

Yush, green light for that, everything is working as it should now :)
