Npc Tony Bowden [Guard from Bo Baronyx] enters in a infinite loop and does not spawn. (Bo Baronyx Spawned 2 times in the same city)

# Describe the bug

Edited title explains.
I edited this issue heavily, because i only noticed it afterwards that there was a second spawn of this specific npc group. Initially i thought it was happening because of a nearby magic academy.
Close to this Magic Academy, there is a church that spawned Bo Baronyx for the second time in the same city/save, Tony Bowden probably is one of his generic guards. This bug probably occured because this group of npc's spawned a second time. I accepted the quest on the first Bo Baronyx, but didn't interacted with the second.

# Steps To Reproduce

1. Get close to a magic academy. (Ignore this)
2. Get close to the second Bo Baronyx

# Additional context

The game automatically enters in debug mode. Apparently this is normal behavior when a npc enters in infinite loop, right?

No source files or tests are named. First reproduce the issue by approaching the second Bo Baronyx with the reported game version and mod list, then trace the NPC spawning and guard behavior involved; done means Tony Bowden no longer enters an infinite loop and the NPC group can spawn and be approached normally.
