When a drawing has been moved out of its correct georeferenced location and you need to move it back using known coordinates as basepoints, you must always scale and rotate as needed in order to ‘force’ the points to match their ‘true’ surveyed position. By ignoring both scale and rotate options within the ALIGN procedure, you are using it as if it were the MOVE command and have effectively marginalized the align command’s soul purpose. This is especially true when a former user has physically moved the line work, for whatever reason, closer to the origin and has rotated the line work a few degrees, however small or unnoticeable, in order to give the drawing a better appearance when printed.
The diagnosis that this drawing has been accidentally ‘nudged’ a few feet or meters out of position is a poor one. Without honoring both scale AND rotate parameters you will definitely get one point accurate and you may, or may not, get the other.
The World UCS orientation is a valid one. Keep in mind that even though north may not point ‘straight up’ it may still indeed, be in world UCS (as is the case when the UCS itself was rotated).
