Bosses not spawning and the "Hunter" quest not granting Mk-18 for purchase

Was attempting to preform Huntsman path "Trophy" to hunt Reshala. Never have seen him once on customs, and I had ran customs alot, more than any map. Increase spawn rate to 100 percent and performed 5 raids in a row on customs. Each time, checked dorms, new gas station, and scav bunker. Never saw him at his designated spawns. I have seen the goon squad spawn at scav bunker quite a bit however. Attempted the same fashion with Schturman at woods. Performed 5 raids to be sure and found he never spawned either at sawmill even with spawn chance set at 100%. Seems that the Goon squad is messing with the original bosses spawning. Force completed the quests so I could continue other tasks. When I forced completed "Hunter" should see the MK-18 for purchase at Jaeger loyalty level 4. Did not see it for purchase at all.
