I submitted a bug report in-game, but I figured I would post here as well, just in case.
With most of the world map, if you hover your mouse over a zone title, it will pop a tooltip that shows your character’s map completion for that zone.
Over the weekend, I was doing quite a bit of map completion in WvW, and I noticed that this feature is missing from EBG (it works fine for the three borderland maps). Hovering over the map title does not bring up the completion tooltip at all. I tried it over the course of several days and on each of my characters, and it seems to be consistently missing.
The completion chart on the left side of the screen is there, but you have to be in the map itself to see that. It’d be nice if this QoL item could be fixed.
