When you open camping and will receive a message from Yelena, she reminds you that the time of the Shadow Gurads are getting going down, but the problem is that you can't even continue when pressing screen, it will not work, no matter how many times you press or restart the game, you'll get stuck on Yelena's message.

There's only way to get out of this, but it's annoying, you have to wait for 24 hours till the Shadow Guards timer is finished and you can finally proceed and play camping.
