Position Tween Crashing Issue #6

[manuel465]

This error is related to the Position Tween and the Undo (Ctrl-Z) features

To reproduce this bug, follow these steps:

• Create a Position Tween (complete)
• Delete the Tween frames pressing Ctrl-Z several times until the object of the Tween be removed
• Open the properties panel of the Tween and pick the option Update Tween
• Create a new Position Tween
• Delete the Tween frames pressing Ctrl-Z until the object be removed
• Create a new project
• Create a new Position Tween. At the moment of defining the path, the path of the previous Tween will show up. If you try to edit that path the program crashes
