Actor Component and Sceneomponent ticks bug

Hello,

Actors Components and Scene Components ticks are not firing

To fix it we have to remove them and add them again in our blueprints and ticks are now firing

Steps to reproduce:

-Launch Unreal Engine 4.17.1 (bug happen with 4.17.0 too)
-Create New Project based on this : Blueprint, Blank Template, Desktop/Console, Maximum Quality, no starter content

-Create new blueprint based on ‘Actor Component’ class name it: “ActorComp”
-Create new blueprint based on ‘Scene Component’ class name it: “SceneComp”

-Create a new blueprint based on ‘Actor’ class name it: “BP_Actor”

-Open “BP_Actor” Blueprint
-Add a new Component and select “ActorComp”
-Add a second Component and select “SceneComp”
-Save and compile

-Open “ActorComp”
-Plug into Event tick execution pin a Print String “Actor component tick”
-Save and compile

-Open “SceneComp”
-Plug into Event tick execution pin a Print String “Scene component tick”
-Save and compile

-Place “BP_Actor” in your scene level

-Hit play

our both actor and scene component ticks event arent running ! that’s a bug !

Steps To fix it:

-Open “BP_Actor”
-Delete ‘SceneComp’ and ‘ActorComp’ from components
-Add them again
-Save and compile

-Hit play

now our both actor and scene components ticks event are running.

Project zip if needed, but it is already with the bug fixed: MEGA

Note that the bug concern Child Actor Component too
