I was trying to search for the typical card description of my pack 1 before I chose the pack 2 in the Jump into Marvel event, so I left the event and searched the card in my collection. But when I tried to rejoin the event, I could not correctly start my play after I chose pack 2. I cannot even drop the event to start a new one. Seems the event says goodbye to me :(

Step to reproduce:
1. Pay 1000 gold to join event
2. Pick pack 1
3. Click "Deck" on top to exit event
4. Click "Create a new deck" but not save the deck.
5. Go back to "Home" and rejoin the Jump into Marvel event
6. Click "Choose Packet", it will ask me to select pack 2 from the same 3 packets I saw in step3
7. Choose one. Then you will see the event page, but still with "Choose Packet" button
8. Click "Choose Packet", you will see the screenshot I uploaded. Precise is my pack 1.
