Thank you, @EsmeeSays, getting someone to take a look.

My team has exactly the same issue like yours in our project on Live server. And it does not even need to be tight space for them to stuck on each other. We can not solve this. Epic has big bug with Walker Spawner. Our public island code is : 0875-2415-4249 , so you can see bug in action there.

This serious bug is real and it is on the Epic side.

Thank you, this is huge bug and it should be solved as soon as possible, we have Live project with every walker stucked.

UPDATE 27.05.2025. : I made small progress on identifying the issue with Island Settings ā†’ Debug ā†’ Navigation Turned ON. And conclusion is that Navigation Mesh does not generate on every Landscape Streaming Proxy element, just on some of them. I do not know what is causing this issue, but at least I figured out why walkers are not moving.

Could you post a video of where this is happening in your island?

Thank you!

Hey folks, while we are investigating, one of the team suggested this as a temporary solution

  • Instead of using one Spawner to spawn multiple Walkers, use multiple Spawners, one for each Walker

I think that it is best that you look directly on our Live Level, its code is : 0875-2415-4249

As soon as you see the walkers in game they will be spawned but not moving.

I will try to make the video as well and send it.

Like I said before, I suspect issue is present because Nav Mesh is not generated on the whole Landscape area, which I figured out by using Nav Mesh debug mode.

And why Nav Mesh is not generating, that is the real question.

Here is the link to the video that explains the issue clearly
