Hello,

In a map with World Partition and no streaming, on spawning BPs attached to each other from a utility BP, saving the level detach the spwaned BP. The issue seems to have been introduced in 5.7.1.

What do you think could avoid this issue?

Thanks,

Paul

Hello,

I tested this in UE5-Main and it seems to work properly now, however, I’m unsure of which cl is responsible for fixing this.

Thanks,

Hello Ryan,

Thank you for your reply.

I am looking at CLs submitted in main after the CL of 5.7, focusing in WorldPartition and Streaming folders but, at least from the descriptions, it is not trivial to me to know which could be the one that fixes this situation.

We will really appreciate if you could give us some leads.

Thank you,

Jose

I asked the team if they were aware of any CLs that fixed this, but none of them knew, unfortunately.
