So, I went to try out the new Challenge feature and upon starting it, when the Challenge Level 2 menu popped up, it literally soft locked me in the menu and I couldn't get out of it.
Just complete the event as normal and accept the the Level 2 challenge and the outcome should be you getting soft locked and the only fix is to close out the game entirely. I seriously hope I didn't lose my badges from this bug too. Cause there's also a bug where they're not showing up as collected in the Main simulation.
