Physics not working after attaching additional component

Hi,

I made a pawn with a movement component and a static mesh for movement with a camera attached. The static mesh uses physics. The problem is that if i attach a widget component / additional static mesh (it seems pretty much any component) to the existing static mesh (root) the physics stop working on the root. The strangest thing is that it happens after the first function call from client to server on the additional component. I even made the function have an empty implementation, still same issue… movement doesn’t work anymore, although rotation still works, so i assume its physics causing it. No warnings in the logs…

Any ideas on what causes this and can i fix it?

I found out that is due to the client being not completed initialized… I first called the method directly after postlogin on the server, but it seems not everything is working at that time…
