[CL] New creature keeper appears every time I travel (within + outside Henford)

I'm playing in a save I've had other issues with since the June update (so I'm not sure if this will be related or a separate issue), but I've noticed there are at least 3 Creature Keepers in one of my saves (including Michael Bell). I haven't played in Henford in my other saves since the update, and have just managed to load my current save today due to other issues.

 It seems that every time I travel to another lot, a new Keeper appears. My sims were at their home at the top of Cordelia Falls, and I noticed over by Michael's cottage there was a different sim labeled as Keeper. My sims then traveled to Henford's pub, and I saw Michael in the village socializing with some of the townies - still labeled as Keeper, and listed as the Keeper on the Henford village board. My sim went over and asked to help him with errands, and while talking to him, the icon that shows his face in the top right after selecting an errand was a 3rd Keeper's face that I have not seen in person yet. None of them are moved into a lot/all are not-in-world and do not have other jobs, so I'm not sure what could trigger this.

I do have mods. I have not tried without them yet, as my separate save issue keeps crashing my game, and I presume it will happen again shortly. 

Thank you anyone for any info :'(
