has this been taken out because i can no find the behavior when i look in the properties of an object?
or is it hidden somwhere else because i cant change a object identifier without giving it the behavior
4ian announced few months ago that the extension will not be supported in the future… Maybe it’s already done. 
I never used it mysel but i was really interested into this feature.
It sucks that it’s being removed.
That was the feature that made me download Gdevelop in the first place when I saw it on the Home Page.
I hope there will be some kinda workaround or new Networking/Multiplayer feature someday.
