Hey there! First of all, thanks for the video! Second, the indicated Whatsapp group doesn´t seem to exist. The reason I am asking is, I´m stuck at 20:21 ... I can copy&paste the ground floor walls to the first floor but they disappear again as soon as I click anywhere. All the time. I wanna cry.
Its caused by not completing the pasting command well. To do it right, after pasting you will get a marquee around your pasted elements, make sure you click outside that marquee region to complete the process. Let me know if you managed. The whatsup group, send JOIN to +267 74409446 I will add you. Thank you
