ChildActorComponent-duplicates when saving new Level
I used to have problems with my ChildActorComponents being duplicated in older UE4-versions, which luckily were resolved. I noticed with 4.13 though, that whenever I save my level under a new name (or overwrite another level than the one I would save to when using ctrl + s) all my ChildActorComponents get duplicated. I didn't do very thorough tests, but here's my example: I have torchholders in my game, each with a torch that is a ChildActorComponent. As you can see in the scene-outliner in screenshot 1, everything is fine: The actor has exactly one torch.
Between screenshot 1 and screenshot 2 I saved the level under a new name (ctrl + s doesn't cause those problems.) As you can see, now the actor has two such components. Every time I save like this, one component is added and unfortunately I don't really know how to get rid of them. I can't select the component in question in the outliner, except if I remove the parent-actor completely beforehand.
Since I did a backup of my level a few versions back and didn't encounter the issue (Just checked: No duplicates in my old backup), I would assume it's a relatively new bug. I hope you have enough info. I wasn't sure what else to add. Thanks for reading :)
