When using the DDT to Adjust the Column Order in a Table Object the UI looks like it overwrites the column below it.   I think this occurs when you delete a column and then move another column.

DDT Locks up when trying to deploy updated database.   Just sits there and runs without any progress made.

Well, there has to be something else in the forumla here.  You can send me your PKG file and I can try to run it here and see if there is some type of issue with the data, but as for the DDT and deployment I need more detail.  This is something that we live in daily, so this is obviously something probably related to your environment or package.
