Hey guy!
I reproduced the bug with a slightly modified ThirdPerson example of 4.14 rocket version.
If you create pawns in the map without possessing them from the beginning and possess them later, it will be reproduced.
Only the pawn of the first player(Connection) can be controlled by RemoteRole being properly transmitted.
It can be reproduced as a linked project.

If you turn on the dedicated server in the editor and run it with two or more clients, you can reproduce it.
Press “k” to possess and press “j” to unpossess.
If you press “k” on the non-first client to possess, the camera moves well, but you can see that the pawn’s control does not work.
