Hi, and sorry for my delay, I wasn’t on AnswerHub for long time.
Well, I solved this issue ! I’ve just migrated all maps to another new project, compiled everything and it worked 
But, maybe I’d like to ask about another issue. I’m trying to package my new project on Windows 64-bit but instead of packaging it’s asking me to install Visual Studio which I’ve never used, never needed because all my code is made in BP.! Also I’ve noticed the Project Launcher which I’ve never needed for packaging neither. Could you explain me what is it for ?
Thank you
