Stuck with child component of a deleted Bp_actor


I have a blueprint actor, which contain Child actor component. I’ve deleted it from the map, and for some reason, the child actor are still on the map, and I cant even delete them

Here is steps to reproduce the problem:

  1. Make a Blueprint actor containing Child component
  2. Put it in the map
  3. Select the Bp_Actor and Replace by Bp_Actor (the same). It will duplicate the child component
  4. Delete the Bp_Actor. The 4 last child component will be deleted with the Bp as it supposed to, but all the remaining child component are undeletable
