RC1 bug: object name same as imagemap name (old)

This is a "known issue" but when the user encounters it, sprites suddenly start dissapearing from the level, which is really really usabilitity wise: www.garagegames.com/mg/forums/result.thread.php?qt=42947
Let me know if you need a recipe for this bug.

Perhaps a related issue:

When Copy-pasting objects to the Level Builder, should not the script name of the new object be appended with ... copy 1, ... copy 2, etc? Instead you end up with multiple objects with the same script name.
