An issue that caused some users to experience a dark black screen after purchasing upgrades has been fixed. Game on!
The issue was introduced in a recent update and had to do with the new “auto place skill into action bar after purchase” feature. This issue is fixed and the new feature works fine. Now when you purchase an upgrade that is a bow type skill (i.e. shoots a projectile) the skill is automatically placed in the next available slot in your action bar. So you no longer have to manually place it after you purchase it by clicking on the in-game skill book. You can still use the skill book and manually place skills, but this just eliminates any extra steps and makes it easier for new players to see and use skills they purchase.
