Hi, So I've been playing the game on PC for the past week, and I've taken out multiple hordes but never got credit for "clearing" some of them. I just got to Sarah and the Militia area and I've only got 25% of the hordes cleared, and I've basically been doing every side quest, and exploring everywhere so I feel like it should be at least 50 at this point.

I killed the ones at the sawmill, there was a drifter camp inside a nero checkpoint and a horde in the tunnel, and a construction/Dump site where they were all sitting in a trench but none of them counted. There were probably more that I don't remember, but I've ran around looking for stragglers and red icons on the map, even on the bike so its easier to see them, and literally everything nearby was dead. I even tried parking near one of their spawn/sleep points in a tunnel quicksaving, and reloading. They respawned, I killed them all, and still no credit, did it like 3 times in a row.

I'm not sure what's going on, it seems like the game isn't counting them properly? Any suggestions or fix?
