No longer required but I am leaving this up for a while in case of issues with the v5.53 patchImportant! This is a bug-fix patch that can
only be applied to v5.50 or later
This patch is mainly to fix the build rate bug for commercial ships and will not affect saved games. To apply the patch just unzip the Aurora553.zip file into the installation directory, overwriting Aurora.exe.

The main v5.50 download already includes this patch as of 19.00 GMT on September 23rd.
