Cant build project after multiplayer added

I have added multiplayer to my project through epic games own tutorials (which is awesome!). After multiplayer added i cant build project anymore, building takes 2 second and hits to an error.

build log: http://pastebin.com/2QWLWrxE

That error often shows up when there is a duplicate file in your project with the same name. When you say you added multiplayer is it possible you added new files to your project that might have a duplicate name?

ok i found out problem for that, i tried all the time build the package into project folder. i changed the location into a empty folder and it started to build alot. (im getting errors from other stuff now :D) probably just gotta clean the content folder its a mess.

this can be marked as resolved
