Any idea? 4.26 …
I had a similar problem. I do not know why, but in the latest versions of the engine, server travel does not work in the editor and even standalone. This works in a clean project, but not mine. It is possible that something is damaged or incorrectly converted from one version to another.
Try to package the project and check again. It helped me.
Yes, epic could fix it…
Thanks for the answer!
