I apologize in advance for my English, basically I am French-speaking and I will use google trad.

My problem and that I can't build walls simply in game with the hoe, I saw on several videos that guys extend their wall with the hoe by clicking on the top of the wall, which has the effect of extend it, when I test the wall does not extend but gains height.

I specify that I play without mod, with the wooden hoe, and the pickaxe of the first boss, please tell me if this technique still works or if an Update has corrected it, or if the guys play in creative or if their stuff can make the difference.

Thanks in advance for your response

Link to the video of the guy using this technique precisely at 2:18 and that I can't reproduce in game.
