UUserWidget::OnLevelRemovedFromWorld(ULevel* InLevel, UWorld* InWorld)

I tried to migrate from 5 to 5.1 and noticed this function has been removed.
any function that can replace it?

Im on the same boat, updating a plugin that worked with UE5, but needed this function.

I had same problem.
I am using
“virtual void NativeDestruct() override;”
instead of “virtual void NativeDestruct() override;” .

@poet are you saying you used NativeDestruct in place of OnLevelRemovedFromWorld? Or you’re just having the same issue with the NativeDestruct function?

NativeDestruct in place of OnLevelRemovedFromWorld.
UUserWidget does not have OnLevelRemovedFromWorld function anymore in UE5.1.
I would like to find Epic’s official saying to fix.
As for me, it works.

@poet okay thank you. For example, if OnLevelRemovedFromWorld is passed two params

(
  ULevel* InLevel,
  UWorld* InWorld
)

Does anything need to be passed into NativeDestruct or is this handled automatically? sorry, i’m new to UE and just trying to get a MultiplayerSessions plugin working properly with 5.1

Here’s the full file for reference.

UUserWidget::NativeDestruct().
It doesn’t take any parameters, but you’re not using the ones being passed into OnLevelRemovedFromWorld() anyways, so it should be fine.
