Summary

When an NPC Spawner is placed on actors like the Concert StageBase 03 Celebration, NPCs do not spawn during the game.

Steps to Reproduce

1, Place the Concert StageBase 03 Celebration in the level.
2, Place an NPC Spawner on the placed mesh.
3, Start the session and observe that NPCs do not spawn.

Expected Result

NPCs should spawn even if the spawner is placed on the specified mesh.

Observed Result

The spawner does not spawn NPCs when placed on the specified mesh.

Platform(s)

Windows 11 and Nintendo Switch

Additional Notes

Temporary workaround:
As a temporary workaround, place a Blocking Volume as the collision for the specified mesh and place the NPC Spawner on it. This allows NPCs to spawn.

Observations:
It appears that the NPC Spawner is considered to be in the air when it is placed on the specified mesh.

Additionally, the Creature Placer Device also fails to spawn NPCs, but the Sentry Device spawns them as usual.

Below is the configuration state when the issue was reproduced.
