A few things regarding this lecture.
Firstly, it’s tag does not appear in the list of tags available 
Secondly, the original crosshair UI widget was a 5x5 square so I believe the actual screen location we need to find should have half the width and height added to the FVector2D to get the actual centre of the crosshair:
FVector2D ScreenLocation(ViewportSizeX * CrosshairLocationX + 2.5, ViewportSizeY * CrosshairLocationY + 2.5);
Lastly, I don’t know if it’s too late to rename those individual lecture tags from “urc_s04_a_landscaping_process” to something including the lecture number “urc_s04_l018_a_landscaping_process” and then sorting them someway? They seem to be in a complete random order atm
