Hey guys,
I love to play Steem Monsters, but since the introduction of the new token system I'm experience a little trouble with the layout on my smartphone.
When I start a battle and have to choose my deck, the left bar disappears when I scroll down the page. I'm using a Samsung Galaxy S7 (Android 8.0) and chrome mobile in desktop mode. Here is an illustration of the bug:
As you can see the sidebar disappears completely. There are also some weird overlaps on the top bar, but they don't bother me.
I think the easiest fix would be to add the CSS property position: fixed to the sidebar, like the topbar.
Could you
