It's not a bug. They revamped Act 4 a couple months ago and reduced the number of overall paths on the map to make it easier for new players to explore. Players that had fully explored Act 4 maps did not have their progress reset and still show 100%. Players that had completed, but not explored Act 4 were upgraded to the new maps, and had some paths uncompleted in order to reflect their previous progression. This allows you to continue your progression without forfeiting any path or exploration rewards.The overall energy required for you to fully explore these maps has is still the same or has been significantly reduced.

Okay but I respectfully disagree, because one of the screenshot that I had attached in the previous post was actually 98% done which means if they didn't update the map I'd be done already now I need to spend a lot of energy just to cover two nodes
