Guys, please help! I'm making a map, and I've finished one side. Now I need to create the second part, making it identical to the first. I'm trying to copy small sections and paste them onto the other side, but I want to mirror it horizontally (or vertically). When I do this (copy a section, mirror it horizontally/vertically, and paste it into an empty space on the map), it doesn't apply correctly and reverts to the initial position. What am I doing wrong?
