I made a test map in UE5 Early Access. I loaded it just now in the UE5-0 version. I think there is a bug unless I made some mistakes. I have a blueprint actor, with other blueprint actors inside it. I don’t know if that is a good practice but at least it worked before. Now, although it shows up in the editor, it is missing upon clicking “Play”, but all the other actors including blueprint actors that only contain static meshes are working fine. While in “Play”, the bugged blueprint actor can be forced to appear by activating and de-activating “Actor hidden in game”.
I have tested this on other maps without World Partition and the blueprint actor worked fine as before, so I’m sure this is caused by World Partition.
