+Between 4MAX expansion 6 and 7, 70+ extra levels were added, that includes some AC Alternate charts that were inserted into slots without AC difficulties, due to the 1000 song hard limit.
+
+Within those 10+ AC Alt levels are 3 levels that were previously part of the 4MAX expansion. Their song ID were shifted to provide space for other songs.
+
+As a result, those three song's score needs to be shifted in the database (song ID 918 > 7, 921 > 4, 722 > 10).
+
+Furthermore, it was discovered that a song has been duplicated. It has been deleted and all score after it must be shifted (song ID 359)
+
+This script does that, simply place in the server root directory and run it.
+
+Everyone with 4max expansion installed needs to run it. If you are just setting the whole things up, this is not required.
