In my oldest and biggest map it seems that it is really fixed for Trackers, but in my other 2 maps their UI is still invisible to players who joined in progress, so I am trying to find out the reason for it. Which means that it still can cause issues in some maps. So feedback from more creators that were affected by this would be helpful right now so we and Epic would know if it is still relevant issue or not. And it could also help in the process of fixing it for Stat Creator in the future update.
