Rounded (arc) wall not working

Hmmm... You should be able to arc a connected wall. I made Rapunzel’s Tower (a round structure) after some complications with the floor disappearing whenever I arched the wall. I think the arched walls are still kind of being developed or something because they glitch a lot. @ Rebecca Baxter

I draw the wall but don't connect it on one side. I end the wall as close as I can to where I want to connect it and then arc it. If I connect the wall, the option to arc the wall disappears from the menu when I click on the wall. After the wall is arched, I connect it afterword by double clicking on the end of the wall to connect the points. Dragging the end of the wall doesn't really work which is why the end point has to be really close to the point I want to connect it to. @ Rivers Grace
