Blueprint keeps generatoring actors from child actor

My player blueprint actor has an attached actor that is the reticle for my player. For some reason, moving to 4.17 has revealed some weird behavior. Essentially, after working on my project for a while I’ll notice in the World Outliner that the reticle/attached actor has been duped several times… and I’ll notice five or ten just sitting at player start. I can delete them from the World Outliner without any effect but I don’t know what’s making them!

Any ideas how I can fix this or at least test it more to figure out the culprit?

Thanks.
