I'm interested in creating a few test mods that purposely cause CTD In specific cells.
Would anyone be willing to share some techniques or methods that would achieve the desired results?

Interesting..... but why?

You could create a reference to an object with a script and then delete the referenced object/item. When you enter the cell it will crash....

.... Why do you wish to make this mod?

I'm working on a system to record cell IDs. I need to know if my current method captures cell IDs before Skyrim decides to CTD.
To test this, I need to have an ESP or/ESM that modifies a cell to CTD. That way when I look at my logs and see if it was recorded.
