Crimson and Clover does not scroll well. To place, build or scroll Crystal Blue Persuasion to where you want Crimson and Clover; without moving the map, choose Crimson and Clover from the park menu and press the green check to build. Wait 1-5 minutes for the check to turn blue. Once it starts building, press the red X, as you also have to wait for it to turn blue. :)

Crimson and Clover has a huge influence, but not immediately adjacent to it.

Also includes the area tools as seen here: http://www.theotown.com/forum/viewtopic.php?p=45651#p45651

TheoTown 839+ will not allow this anymore!
