On Windows 7, using version 1.0.64, when starting the game while offline, I get an error message that says “Lorum ipsum …” (always thought it is “Lorem ipsum”, but maybe we use a slightly different version in German), having two buttons that both do not seem to cause any action, the game seems locked up.
[1.0.64] Lorum ipsum when offline
This happens to me as well, version 1.1.00.
