When you create a raid, some of the raiders may be missing, they have traveled pretty far from the village most likley. When i start a raid the raiders run away from the village making them extremley hard to find. 

Steps to reproduce:

1. Start a raid
2. Kill the raiders you see
3. Look around for others 

Observed results: some of the raiders walking away or missing from village

Expected results: raiders will be close to village, easy to find and kill
