Didn't notice u can only sell barricades, maybe i read the tutorial too fast and didn't see that or that wasn't explained so don't take into account the first bug i mentioned but the bug of the sell button not appearing if ussing the keys or the third bug that i have to spam both clicks to sell are still bugs and not a misinterpretation of anything
For the rest, i don't know why u are explaining the destroy button and that i need the movable upgrade before moving a placed turret, maybe u missunderstood something that i wrote or i didn't explain myself correctly if u can do as when u answered the other post of requests doing the "for the edit1, for edit2" and so on so we can better understand each other
