UE4.0.2 multiplayer messed up editor?

I was trying to follow the blueprint network tutorials - YouTube but every time I try to run the game with 2 players the second window ( titled client1) was messed up and there wasnt 2 players on the map like in the video.
After I put some debug text if they have authority or not I noticed both windows reported to have authourity.

Right now I am unable to test or try the multiplayer if all clients and server claim to have the authority.

Could your problem be because both players are attempted to spawn at the same spawn location?

as answered in this post:

Even if I add multiple playerspawns the result is still the same.Maybe that is a bug that will be fixed in 4.1 which will be release next week :slight_smile:

It is a bug in 4.0.2 and was fixed in the 4.1 preview build so it hopfully still is fixed in the final version
