Came across this bug while building a Sprite Font. Really cool feature, by the way. :)

Steps to reproduce:
1. Be sure that the event that sets the character width of the number "1" character to 4 is enabled.
2. Run the layout.
The "1" character has the correct spacing, but now the "2" character has become corrupted.
Changing the width of the "1" character should not corrupt the "2" character, pretty much. ;)
