I play with my Hubby on a Random Gen Map.
Twice we have accepted this clear quest from Trader Joel and cleared without problem until there is one little dot left.
In the Generator room there is a locked door with the target behind it, however we cannot find a trigger to open said door so have broken down the door (first time) and gone through the wall (second time) to discover loot boxes and no zombie, just his marker dot 1m away sitting on the shelf, or under it.......invisible zombies, who'da thought!
We have scoured the PoI for a button or lever to remotely open the offending door without success and, as previously stated, we have replicated the bug by accepting the quest a second time with exactly the same result.
