Field of Frustration (Bug, or just me not seeing something)

Issue: Subscribers clumping up, throwing a tantrum, and mass-unsubbing after visiting an inn.
Crash: No
Platform: Mac
Description:

After playing for a while I noticed that in one particular area, subscribers seemed to all gather in a clump before growing frustrated, throwing a tantrum, and unsubbing. About 60 did this before I realized what was happening. They all picked up a quest immediately beforehand, leading me to believe the issue stemmed from that quest. The most likely quest to cause the issue was a traveling quest to set their home at a nearby inn. The inn wasn’t full, but I had recently moved its location slightly, which I think is what caused the issue. Also could be an unrelated coincidence. The subscribers seemed completely normal until arriving at the clump, and when the clump temporarily cleared, more continued to arrive with the same results. Any idea what that might be about?
