RTW has sometimes a CTD, if you solve it simply by reloading, be happy and continue with playing.

In any case has the just existence of a character (your Tvrdvs) in a region (in your case Greece) nothing to do with a CTD in your game. This is not related.

The saves are located in EB\saves; but I doubt uploading it will help you come across individual and not repeatable CTD's.

BTW: You know about the EB-campaign-script?
