When I choose one of the floors drawn side by side in the attached project and want to move it, I encounter the attached message. I do not encounter any error messages in geometry control either. Where is the problem? I also see that the problem with node porting is back in very old versions (maybe V3-4). What could be the reason? Namely: When you select objects with the Move node command, if a new node is moved to an existing node, the move does not take place. Although both of the issues I wrote above are issues that I have encountered before, when I encountered them again, I felt the need to write. Take it easy everyone.
