Getting a strange Exception Error

I'm specifically trying to target this area in my structures.yaml file:

Code: Select all

However, not only can I not remove SAM.cuba and ~!structures.cuba (it results in an exception), it seems that any tampering of this file at all generates the exception too.

The exception is listed here:

Has anyone been in this situation before? I'm afraid to even modify any particular numbers now that this error started popping up.

Any help is appreciated!

Shouldn't Cuba Sam inherit defense not sam? Inheriting SAM would duplicate everything.

Well the spy and its British counterpart use this same pattern. It works as is. The only problem is altering and deleting this pattern, and it seems to be a problem when I touch the rest of the file as well.
