I resolved Indomitable Creativity for X=2, and Titan of Industry + Atraxa, Grand Unifier entered the battlefield—their ETB triggered as normal. I stacked the Titan trigger on top and the 4 options showed up. I selected the Destroy artifact/enchantment option but didn't submit, then clicked to view the battlefield, clicked or highlighted opponent's Veteran Survivor to see if it was enchanted, went back to the browser and the 4 options had disappeared and the submit button was greyed out—I couldn't select anything. I tried pressing Z to undo, toggled between battlefield and browser, clicked on opp's creature again, clicked on Titan, but the box of options remained empty with a greyed out Submit button while the timer was running out. I ended up timing out and not being able to resolve neither the Titan's nor the Atraxa trigger.

I attached a screenshot of the board state (with 17lands) and you should be able to navigate the game and find the event on my turn 5 through this link: https://www.17lands.com/user/game_replay/20251213/e2813e2e612c4e0a8cb4a01a9ff75162/90
