Location bug in lectro city

In lectro city I have discovered all 8 locations but it’s telling me I’ve only discovered 7/8 please help its the last one for the trophy

You should have discovered:

  1. The Underpass
  2. The Hills
  3. Downtown Square
  4. Market Quarter
  5. Meridian Seaport
  6. Big Dock Energy
  7. The Plant
  8. The Bone Zone

There have been issues if mix-play with other people while discovering locations. Don’t know what the status on this issue is.

For visual help (little dated, haven’t updated these with recent loot pool adjustments):
