Fortnite Ecosystem GDC 2024 with Known Issues

Known issue: The Rocket Racing Vehicle Spawner is currently unusable on Android devices due to the absence of touch user interface (UI) support. A fix is planned shortly.

Known Issue:

We’re aware of an issue with the NPC Spawner failing to spawn an NPC when there is no custom NPC Character Definition data assigned to it. We are working on a fix, but in the meantime, you can use this workaround.

1. Select the affected NPC Spawner Device.
2. Click on the NPC Character Definition option
3. In the pop-up window, choose to Creative New Asset → NPC Character Definition
4. Configure the definition data with Character Type and associated Modifiers (Please refer to this documentation for details)
   

The NPC Spawner device should now work properly and spawn the NPCs.

We're aware of an issue with the NPC Spawner failing to spawn an NPC if they have been published before 29.01 is released. We are investigating the problem and working on a fix, but in the meantime, you can use this workaround.

1. Select all NPC Character Definition assets in the content browser (you can use the filter to do this easily).
2. Right click on the assets
3. Choose Save to force resave all the assets
4. Re-publish your UEFN project.

After that the NPC Spawner device should now work properly and spawn the NPCs in your published experience.
