Same issue

Same issue, on windows, picked Incredible and Wild. Kicked me to home screen. Reentering the event shows me my first pick and asks me to confirm my pick but the button is greyed out and there's no options for a second pick

Same issue, on both windows and ios. I started the Jump In selection on Windows, picked Iron Man, (blue) went to the second packet and picked another mono-blue packet. Kicked me out. When I reloaded the game, I can see the event and click it, and get a button that says 'choose packets'. Clicking that button takes me to a screen titled 'Choose one of these themed packets' and I see the iron man packet is picked, but no other choices, and 'confirm pick' isnt lit up so I cant click it. Same behavior if I try loading the game on mobile.

Had the same experience. Picked Battalion (mono white) & then Counter Argument (mono-White), then got kicked to home screen and when I try to enter the event again, it shows me the "choose packets" button but when selecting it, it shows that I've got battalion selected but wont show the choices and can't do anything in the event currently.

+1. The packs in my case were DOOM and Master of Evil.

This just happened to me as well. I'm on Android. Edit. It works now. Just had to wait two hours.

+1
