In the level editor, over by the pre-defined objects is a button that has a flame on it. This destroys the currently selected pre-defined object. Stefan, could you please add a warning message for confirmation that you actually want to delete that pre-defined object?
For example: I wanted to delete the "House" pre-defined object, so I select it, click on the "Destroy Pre-Defined object" button, and it pops up a little window saying something like:
NPC Code:
Are you sure you want to destroy this?
Yes No
I'd really like to see this, because I often waste minutes re-building the pre-defined objects for something like the castle tiles because I accidently clicked on that button.
