That's a valid point. If you reread the original post, i CLUAed Aran into the dock area, ar0300, and attempted to run the dialogue with Aran. The game froze up and after 2 or 3 seconds disappeared, just like it did when i entered ar0307. At that point in time i assumed that the dialogue file was the culprit, now i'm not sure. I'm sure that you are right about the name of the thread, but, i really don't know how to change it, unless i simply start all over again.
For Shuv-Oohl; "But again my question: You do reset the game after a fruitless intent of finding the culprit to it's prior state, don't you?"
The answer to your question is not all the time. If i find something that is wrong, but easily correctible, i correct it and then make sure i don't see it again. I keep track of creatures that i have altered so that the game does not crash. My list shrinks and expands frequently.
I did CLUAConsole in all of the creatures that are listed for the area without any problem. I can only assume that they are not responsible for the freeze. One small piece of information that i forgot to add, i have tried to enter with all of my equipment and also without any equipment, just in case i was carrying and item that i shouldn't. Same result.
There is also, my small workaround, that doesn't always work; timing is crucial, i used CTRL +J to move next to Aran the first time i enter ar0307 after the Underdark and it worked, but, again it only works immediately after the Underdark. After you kill Bodhi, the amount of seconds before the game disappears is less.
There is probably more, but i have forgotten them. I suspect that i will have to reinstall and omit 1 or 2 mod components and then do as little as possible in ar0307. That may make a difference after the Underdark, or maybe not. In which case a year from now i'll be as confused as ever.
But i haven't given in yet, close, but not yet!
