So today in the hard challenge you have to break 20 lucky blocks in lucky islands and kill 2 players in lucky islands. It doesn't specify solo or teams (I did the challenges in both anyway,) and it also doesn't say you have to do it in one game (which I have definitely done as well.) After doing this, it doesn't say I've completed these challenges. I've relogged, and I completed the challenges a few hours ago. They still have not gone through. Could someone help me or explain what is going on?
