-Properties concerned: an array of vector, a boolean, an enum, a reference to an actor.
-Step to reproduce: i dont have exact step but i didnt suffer from this bug before i reworked the code. was working fine when it was simple blueprint based on actor. i reparented most of my blueprint to have parent and made them to be child. Since i did this, i have now some childs properties (and always the same properties seem to be impacted) are reset when i restart editor
-Project information: limited to this project as i use parent&child for the first time
-Project created in 4.8 if i remember
-i think i dont have circular references (circular reference mean that i have a reference of my child in my parent and a reference of my parent in my child?)
as usual sorry to not have steps to reproduce this, but for sure it happened when i rearranged my code to parent&child
i will try to make a blank project with parent&child bp, and then try to see if i can reproduce the bug and send you this project
