Kalypso has released the 1.06.2 patch for the box retail copy of Disciples III: Renaissance. The patch fixes some AI issues, problems with the Hotseat mode, user controlling enemy cities, and other issues (full list). Note that this is only for the boxed retail version, not for copies digitally purchased (Steam, Direct2Drive, etc.). Digital purchases will/have already been automatically patched.
For those customers who are getting the “Disc not Found” error, do not install the patch: contact firstname.lastname@example.org for a specific fix.
