If I have this class:

```
UCLASS(notplaceable, transient, MinimalAPI)
class ADefaultPhysicsVolume : public APhysicsVolume

```

And then try to inherit from that with this:

```
UCLASS(Placeable, NonTransient)
class VRBASE_API AAdvancedPhysicsVolume : public ADefaultPhysicsVolume

```

Then it still doesn’t allow me to place it into the level or create a Blueprint from it.

I saw this mentioned as an issue that was first introduced in 4.21:  
[UE-77205](https://issues.unrealengine.com/issue/UE-77205).  
But it’s marked as “WontFix”, which is a shame. It really puts a limiter on what you can do with the engine sometimes. Is there any reason to even keep the Placeable class specifier now then?

Did this issue ever get resolved? I’m seeing the same thing in UE5.
