Yea b/c coed from existing races is often used to make new ones so if there is a bug in an old one it will be in all code that uses that code. Thus a new standard model for how to code that code is required and all must confirm to the model to prevent bugs. Even if it does not help night elf it should not occur and is thus a bug and thus needs to be fixed. The fix is fast and easy and was done right away.
