Blueprintchild Acts weird - Showcase before Bugreport

Hi folks,

I noticed a weird behavior on on of my Blueprint (Type:Actor) Childclasses.

What is weird:

After creation, child acts as expectet. After PC reboot the Static Mesh Actor Component got Stock on World Origin (WorldLoc 0,0,0):

The Static Mesh Component is stuck at World Origin. The rest as seen above (BoxCollider with Arrows) is movabel.

The Child is just a Blueprint Childclass. Nothing changed, except the Arrows are rotated by Local Z 180°.

How to fix (temporary): Delete Child Actor in Content Browser, recreate Child, place in Level:

Restarting the Enginge by closing an reopening will trigger this behavior ALWAYS.

For notice:

  • No Constructionscripts in any Parentclass or the Childclass!
  • Buggy Child is a Child of a Child. The here showed Parent class is the Child of the “Root” Class with all the behavior on it.

Any opinions? Is that a bug (I think so)?

Thanks!

Update:

Fixed it by setting Static Mesh Component named SM_Tile to MOVEABLE in che Child:

BP_Structure

SM_Schleuse_Waterplane was Moveable the whole time.

What is still weird: On the Parent, SM_Tile is set to STATIC an SM_Schleuse_Waterplane is set to MOVEABLE the whole Time and it was an is still working!

Is this my fault? Or is this an Engine bug?
