Has 'Building the world partition minimap' ever worked?

I’m currently testing a functionality in Unreal Engine 5 to see if it has ever worked. It’s when you build the mini map that appears in world partition and lets you load and unload world partitions inside of a level. I tried in Unreal Engine 5.7 today and it never finished after like, 10 minutes straight of just doing nothing other than consuming GPU and RAM. example below. I started it and left it, came back 10 minutes later and it was still doing it.

So then I tried it in unreal engine 5.4.4 In a brand new fresh project. Still, the exact same result. Just created a new level, enabled world partition, and started trying to build a minimap. It simply does not work. Like it just does nothing. So it’s been broken in 5.4 and it’s still broken in 5.7 apparently, so I guess there’s no way to build a minimap or load and unload world partitions? I don’t know how that can make sense

worked in 4.26 last time I checked it.
They tried to cut out world partition - which really is the only option that works - for world composition which never worked right since they attempted to force feed it to users.

It’s not exactly unlike Epic to force people into the new thing by causing irreparable damage to what used to work… Actually, it’s their playbook…

Sorry just to clarify… what is the “new thing” I should be using? Maybe I am indeed missing something and didn’t catch wind of something I should’ve as a newbie.

World partition vs world Composition I think
