Ok so i have no clue what is going on.
In my project i have more or less a basic Character class.
My problem is that when i run the game with a dedicated server i cant move.
Same goes for the second client joining on a listening server.
The first player (listening server can move) but Movement dont get replicated.
I have set the replication propertys to true.
Am sure i read somewhere in the docs that ACharacter replicates movement by default.
And everything did work before have any one had this problem?
Solved.
For anyone that may do the same dumb mistake as me.
Dont put the dam function as protected
