The deckbuilder is pretty broken lately. At least for me. You try to replace cards by dragging a new card into the deck but nothing happens. Removing it first doesnt help. Even removing an entire theme wont help because adding a card to an empty slot doesnt work either.
Sometimes it works to use the arrows at bottom to change deck but most of time its complaining there are not enough cards in deck, autofill, etc.
I recall having similar issues during the last card event. Have to keep trying, going back and forth to the deck builder. And trying over and over.
Not sure if it matters but it is deck 4 that I keep trying to change.
OK, just noticed it has now completely messed up my main deck (deck 3) now. Wasnt even the one I was trying to change and the cards are not the ones I was trying to add.
I think so. What I know for sure is that I was trying to modify deck 4 and doing drag and drop to replace cards did not work. Nothing happened. First removing a card then doing drag and drop also didnt work, that left an empty black box. SOMETIMES it would work to change deck from 4 to 3 then back to 4 and you would see it had actually correctly updated the card but most of the time when you tried to change deck it would tell you there were missing cards and you had to auto fill. And yes, after doing that back and forth for a while then leaving the deck editor and coming back again, I saw that my real deck (number 3) was messed up.
In the end I gave up and tried some hours later and it worked as intended. In that case it was a 100% fresh start of the app, while it is quite possible that the previous case (where I was having issues) the app may have been in the background a number of times (like opening the game, donating some card, turning off phones screen, turning screen back on an hour later, open a free pack, etc). I was doing other things in the app just before the issue though, so it was not completely out of sync or disconnected or anything.
I have had similar issues with the deck builder quite a lot of times in the past.
Oh yeah, and Im also not sure that the changes made to my deck 3 are exactly the ones I was trying to make to deck 4 either. It has gotten some of the cards I was trying to add and others I was not. But that may have been because of the auto fill.
Also, the deck I eventually used, that did work, was deck 1. I am going to restore my deck 3 sometime today, will post an update if it works or not.
Both restoring deck 3 and making a new deck 4 for the neutrals event today worked fine without issues. The game was freshly started.
Will try to keep track of it in the future, still suspecting it may be related to the game being in the background for an extended period of time before trying to update the deck.
