Hello
I also have the English version 1.0.13.67. That is the International UK version, and is the latest.
All other versions beside German and US are behind in patching (even though some fixes went into the US version that is NOT in German yet...).
I actually got burned and ordered the International version by mistake (not knowing the difference...through Gogamer), so I also am perturbed.
But, our versions are up to date in their respective countries. A few newer fixes are in the US version that makes the game faster and more reliable as well as a few new features..and Larian is trying to bring out that patch.
More info is in this post.
