What you were expecting to happen, and what actually happened
The menu for filtering/sorting minions is invisible. It works when you click however…
How often does this happen? When did it begin happening?
All the time. I spotted it todayin the morning (around 6 gmt).
Steps to make it happen again
It is visible at first, but as soon as you upgrade any minion it vanishes, and does not come back even if you switch tabs.
