"Blueprint Multiplayer" Video Series is teaching a lot of wrong things

Hi!
I just watched the series three times in this week and followed it but my project always end up with lots of issues or completely breaks. Only now I realize this post and ■■■■ I wish I saw it before. Anyway, I appreciate all the work done into this tutorials and I really wish a new series coming out to teach us the right way.
you’re a legend. many thanks for the post.
@ I double that. I wish if people who know better would jump in and create a tutorial series.
I may suggest that a maybe two people come together and create the series. Maybe one will do UI videos only other will do Blueprint videos?

Many thanks
