Definitely. It is game breaking (you literally can't progress) if you don't know how to solve it like we did. I think they spawn there. Done it over five times now for testing. Every single time there are 2 AAF members stuck. Removing/Changing their spawnlocation should already fix it.

You will find that there are AAF members stuck inside a rock. This is the rock behind the high watchtower (where there is a guy you have to spot as soon as you start the mission). If you lay down on this rock, you glitch through yourself and are able to spray down the last *two* AAF members.

My crosshair points out the rock:
