Also, one thing that I forgot to mention is that the indivdual stacktrace lines could be extended with the origin of the python files.
Since the File "..." part represent a python __file__ attribute (which I would assume the engine keeps track from which exact python file it comes from), it would also be neat for the end user to know exactly where that python file came from.
In the case of a base game file it would be enough to just output "TS4" before the "File ..." part, while with modded scripts it would be good to display the name of the .ts4script file that it comes from or the folder that contains the Script folder from which scripts are loaded.
