Summary
As of the latest 36.00 update, child actors that are attached to a parent actor do not correctly inherit the parent’s world position after being culled and then reloaded into view. When the camera moves back within render distance, the child actor reappears in an incorrect location—often reverting to its relative transform without accounting for the parent’s world transform changes that occurred during the culled state.

What Type of Bug are you experiencing?
Stability
Steps to Reproduce
- Create parent → child hierarchy in outliner
- Move parent object via verse or sequencer
- move player/camera away far enough to cause parents/children to be culled
- Move player/camera back towards objects to render them again
- The child actor(s) is now out of sync with the parent’s current position., and there are “ghost” collisions where the actors should be…
Expected Result
Child actors should reappear in the correct relative position, accounting for any changes to the parent’s world transform while culled.
Observed Result
Child actors return with incorrect positioning, as if frozen at their last known transform or reset to a default.

Additional Notes
This issue breaks visual fidelity and gameplay logic for setups using dynamic parent-child actor relationships, especially in large or open-world environments.
