AI not working anymore after moving it to new level

Hi. Yes, the navmesh is loaded. Now I see that there is a RecastNavMesh-Default after I hit the play, but it’s inside the main level. The error comes from the ChaneNPCSpeed because I can’t cast the NPC_AI and the speed remains at 0

Edit: If I check ‘Always Loaded’ on Gameplay map it’s working. If I load the map with blueprint it fails. It seems that NPC_AI is trying to cast to NPC but NPC it’s not yet loaded.
