Has the bug that fences create concrete floors been reported yet?

Are you using the fence tool that makes a square that you drag to size? I haven’t had any trouble fencing in gardens with the fence tool, and I use the regular tool you use to draw each side individually.

I do draw each side individually, the problem is that I had an open "gate", and when I fill that in so I can put a proper, lockable gate there my whole carefullly landscaped garden including pond disappears and becomes concrete.
