Editor closed upon trying to move Conditions while working on a smart_Script

[Editor bug.txt](https://github.com/BAndysc/WoWDatabaseEditor/files/11131026/Editor.bug.txt)

Basically i was working on a Smart_Script for an Escort quest in WoW, When i (in mind) had an solution to my problem i was facing the editor crashed, I've created a new Row for a Smartscript in the Editor and tried to Drag n Drop the Conditions of a previous Row to the new one, then the Editor closed up on me. So im guessing it has something to do with Drag n Drop and Conditions.
