I've done the test where I started to move the card back and fourth from its original placement. 

Here's the video of the gameplay for reference: https://drive.google.com/file/d/1CcLb1q1EeAG6R-3_eTwgoLoXsc-MIkeh/view?usp=sharing

I found out that during the round 7th, min 6:50, I moved the card Crypto Zen 1 slot down, and suddenly I didn't have the button DONE available to me anymore. The only button I had was PASS, showing that the system got confused already at this part. 

Then I had Brando streaming his match on the discord, so I could see his screen as well and what was happening on his side. I noticed at that point that my card didn't move on his screen, but on my screen it had moved. Then I tried to refresh the game on my side to see if it would fix the problem. 

After refreshing the game, I realized that the card was back at its original position, so it didn't had moved as it had appeared. However, after refreshing I wasn't able to move that card again as I was getting API error.

In my opinion, the system is getting confused when moving too much 1 card, or even perhaps when moving many round with multiple cards. 

The video of the gameplay is there to show every movement and click for reference. 

Hope this helps to solve the bug issue, as I believe this is the root of all the other bugs we are getting it at this moment.
