Well, the scripts are different per category and I've only been dealing with the units, so the 'sim' category, but reloading scripts isn't a problem. Refreshing can cause a crash, if you have a behaviour or unit selected which is not loaded. When you first load the AI debugger, select the category, then click refresh, BEFORE selecting anything in the second drop down, as for whatever reason, it will list all the old behaviours that may not be loaded and will crash the game if you try to access them. For example, if you are looking at a ship that sinks, then pressing refressh the game will crash, as that unit no longer exists.

EDIT: Oh yeah and if you muff up a script, it will crash the game if you reload the scripts, but then again the game won't restart with muffed up AI scripts.
