This is annoying.
I copied all components pasted in text editor. there is nothing from where it could get order information, just the lines itself. so i reorginized it that all components where sorted and copied from the text editor and pasted back in components. no luck.
Then i created a complete new bp and pasted it there. no luck. i mean the paste from the texteditor copy worked but its not ordered like in the text editor.
so it seems that something is somewhere saved deep in the engine or project code which takes the order information.
i also would like to hear from epic why we can not just have something like a reorder submenu element, that just would simply reorder by name.
