Could not complete the clear/fetch quest on A21.1 B15 public test server.

Another player (NekoPawtato) also checked the POI just tp make sure that I did not miss some zombie.

Here are all the spots we checked after I went over there to help look for the missing zombie(s):

 

I think the issue here is, even if you finish clearing the zombies and haven't grabbed satchel yet, if you relog or disconnect, the zombies all respawn and the game tells you that you have to clear the area again. At least when I tried this in singleplayer, it doesn't make you "start" the quest again and reset the place. Which means if you hit the button in the tower before you disconnected, that switch doesn't reset. And because some zombie spawns are tied to that button trigger, you're not going to be able to get those zombies to spawn back in to finish your clear quest.

Nevermind might be a singleplayer vs dedi thing

Thank you for reporting.

Confirmed that the clear part of fetch/clear quests cannot be completed on a dedi if you exit the server after acquiring the quest item.

I will write an internal ticket for this issue.
