Players getting stuck after servertravel

So after some testing today I’ve come up with some results.
The same bug/problem seems to be present even in a fresh firstperson-BP project.
Extra details on the new project: For fast integration with steam I used the steam setup utility (found on the forums) and it does a nice job, allowing steam overlay and online sessions to work quickly in the new test build.
The new project has 2 levels, 1 “menu” level displaying a widget that basicly joins the first found session, and one transision level “transmap”.
Enabled Seamless Travel in game mode.

This time the test was done with 1 client as listen server, and 2 clients connecting to that session.

Randomly clients would get stuck in limbo after server executes servertravel,
The problem occures exactly as it did before. The affected players can be seen in the console log of servertravel command.
