They didn't just disable it, they removed the whole code for the GUI. That means their codebase is the same as ours but with the GUI. This issue is not in the GUI (indeed!) so it also affects their codebase which is why I submitted it. They won't add any GUI for the structure blocks (Please, don't do it ! I like it this way) but they could fix this.
I know, I worked on it to make it work but that doesn't mean it isn't an issue ! Actually, it won't work for them either so I guess we would both be happy if they were to fix it
It is "LEFTCONTROL".
Ah ok ! The "right" as "correct" 😉
I just found the problem, it was just an introduction.

No they did not disable it completely, it is just the GUI. Trust me, I've worked on bringing it back. This issue doesn't concern at all neither the GUI nor wether or not the block should be in the game. It's just a simple path problem.
