This was the 3 rd time I could not enter the chest war at World boss although I was ranked 4. Whenever I click on the place where I should click to enter the treasure hunt opens. No possibility to enter. It happened to others of my server too. I am not new at WB and was fighting in chest war from the very beginning of instalment. Cache was already empty due to the check in problem. So it is not a matter of cache. Please check and solve this problem!
