I promised the patch to be released after two weeks. Owing to my procrastination,
I am doing it only now, a week later.
The patch contains:
BlankFieldPlates added to airfields,
Poznan historical fortification,
several smaller towns like Pabianice and other added,
most of airfields tested by betatesters,
issues on takeoff and landing AI behaviour repaired.
The patch does not contain missing 3D objects in some town and city suburbs and humlets. These areas would be necessary to make consistent also in 1944 and 45w versions of the Poland map, what is quite huge amount of work, and, moreover, of testing. Therefore it might be done in some future, after release of the Yugoslavia map.
The patch was tested on 4.12.2 SAS 5.30 Il-2 version, it may be downloaded here or at the first post of this thread.
