Screenlock by clicking on Custom Campaign quickly

*Version:*

2.0.7f1

*Description:*

When you click on the Custom Custom quickly (doesn't need to be as fast as I do in the video), your UI won't show up.
I assume this bug get's triggered when you click on a button before the UI pans in completly.

And I dunno if you have to click on skirmish before or not, but I did.

*Steps to Replicate:*

- click on Singleplayer

- Click on Skirmish

- back out of Skirmish

- click on Campaign

- click quickly on Custom Campaign before the UI finished paning into the screen
