IL-2 Sturmovik 1946 coop missions patch V1.0

marathon


IL-2 Sturmovik 1946 V4.09 contains six .mis-files with design errors that makes it impossible to have RED WON ! or BLUE WON ! or both in them.
They have not been fixed in patch V4.09 or any other patch before that.
I wanted to change as little as possible to respect the work of the original mission designers, and after patcing the missions we also completed them in this marathon to see they really worked.
Below you will find the patch and information why those missions were not working properly, what needed to be fixed and how was the mission changed.

IBCo-op1-Stalingrad.mis RED side
What is wrong with the original mission?
C:\Program Files\Ubisoft\IL-2 Sturmovik 1946\Missions\Net\coop\3IBCo-op1-Stalingrad.mis is misbalanced and BLUE WON ! is 99% impossible

Bugfixes were based on this information:
RED WON ! will always come between 16-19 minutes when 15 red tanks will destroy 50% of 9 blue artillery units inside the circled area of size 350 before 20 minutes has passed. Also3 red bombers will bomb same blue artillery units and 6 red fighters are escorting them. Red tanks will always destroy these 5 blue artillery units even if all red bombers and fighters would stay in their home airfield and never take-off (This was tested by taking a seat in red leader plane and never taking off). So blue fighters would have to ignore those red bombers who will only make one bombing run and then leave and blue fighters should destroy red tanks, but they do no weaponry capable of destroying 4x red KV-1 and 8x red T-34. Only tanks that can be destroyed are 3x red SU-76M because they have open top, but even those would require blue Bf-109 E-4's 20mm weapons because blue I.A.R. 7.92mm weapons can not destroy them. Even if 3x red SU-76M would all be destroyed by 2x blue Bf-109s available, still other 12 red tanks would destroy too many of blue artillery. Blue artillery will always manage defend and to destroy 1-3 red tanks, but not more since 6 of these 9 artillery units are 150mm Howitizers that are totally immobile and can not correct their aim when tanks have moved away from their shooting area and ofcourse they can not shoot up to hit red aircraft. In theory the best thing blue could do is to kamikaze all its planes into tanks, but even if by some miracle there would be 6 human pilots that all could collide with a red tank and destroy it without beeing shot by all those red fighters on their tail, that would not be enough since they could only destroy  5 tanks by kamikaze and still enough red tanks would still be available to to destroy that 5 blue artillery units required. In other theory blue planes could also land behind red tanks and move around in ground close enough the red tanks, so they would turn their turret to face blue planes and not blue artillery, but I suspect there are no 6 human pilots who could survive like that so long that 20 minutes that is required for blue artillery survial is reached. Also blue take off airfield is too far away to have too enough time available to properly try aforementioned theories.

3IBCo-op5-ConvoyChina.mis RED side
What is wrong with the original mission?
C:\Program Files\Ubisoft\IL-2 Sturmovik 1946\Missions\Net\coop\3IBCo-op5-ConvoyChina.mis is using "Target Ground" for non-stationary units which makes RED WON ! and BLUE WON ! impossible

Bugfixes were based on this information:
It is a know fact that Destroy Ground can not be successfully used on non-stationary units, not even if all waypoints are set inside Destroy Ground circle. So one stationary object needed to be moved near non-stationary objects last waypoint. Because the moved stationary unit is placed near original units last waypoint, GATTACK can destroy this one stationary unit even if it is not really targeted. So both AI or human players do not have to know that RED WON ! and BLUE WON ! only depends on if this one unit is destroyed or not.

Bugfixes in FMB editor:
Changed Destroy Ground circle location slightly.
Changed 68_Static originally located faraway in blue territory inside Destroy Ground circle.

Fixed coop missions where mission objective actually always works now makes it harder to just dogfight and collect big scores because you have to concentrate also on ground troops too. This is why it was not so easy to do new team records with just a few tries we reserved time for.
