Descriptive Problem Summary: The map editor's nudge feature shifts the position of all like objects on the same z-map. It should only be shifting the selected (or last placed) object.

Here's a test project I reproduced it in successfully three times.

Numbered Steps to Reproduce Problem:

1. Place one of the nudge testing objects down in the map editor and compile.
2. Place another of the same object.
3. Begin nudging the last placed object in any direction via Shift + arrow key. You should see every other like instance moving too.

Expected Results: For only the selected or last placed object to be shifted.

Actual Results: All like objects are shifted.

Does the problem occur:
Every time? Or how often? Every time.
In other games? All games.
In other user accounts? N/A
On other computers? N/A

When does the problem NOT occur? It doesn't. This has been an issue since the introduction of pixel movement when the shift function changed.

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit http://www.byond.com/download/build to download old versions for testing.)

N/A; see above.

Workarounds: I've been manually editing objects' offsets, which gets very tedious when you want something specific.
