Spline not editable when set in Construction Script

It’s a pity… Well, maybe some C++ folks would know how to change it via cpp…

That’s interesting, in my case it doesn’t work. I’ve tried plugging this:

… Into Event Tick, Begin Play, and other places… Still, the point doesn’t change its location during gameplay. I have around 7 points in my spline (set in construction script) and I’ve tried changing location of spline nr 0, 1, 2, 3, 4… None of them changed their position. (However, it works when I disable Construction Script and add points manually in editor)
