The patch 1.8 includes lots of bug fixes, including some large improvement on the game localization (over 200 changes).
Please note that due to some much needed fixes on a few maps, pre-1.8 saves are no longer compatible on those maps only, requiring players to restart their on-going games. Here is the list of the affected maps:
- Princess of Varn
- Succession Wars
- A Tale of Two Guardians
