There was a few bugs, but nothing serious:
Lets see.
- air start with engine stopped on some missions
I cant be sure but I dont think this particular bug have anything to do with lightened up air.ini.
Does playing without lightened air.ini cures the issue?
- missions loading at 100%, but I got a "blank" screen (without plane) or a see-through plane
Sometimes when I am using QMB, I am getting "mission loading null", I am guessing it might have something to do with "Mission Pro Combo".
In any case, click Chose side: Allies /Axis button in the top right corner of the screen, it will fix the issue.
Currently I am not well and if I feel better, I will look into it.
Here are some other causes I can think of:
Those air.ini reduce number of aircraft loaded to boost fps, instead of mindlessly removing random aircrafts I tried to create theatres of war so, despite missing half of planes in game, you wouldn't miss on anything as long as you stick to particular theatre.
Now, it is possible you chose Pacific theatre and then tried to play mission/track which included German or Russian planes, in this case you would get a missing plane.
If you load 1936-1943_air.ini or 1942-1945_air.ini and play campaign, you will get only some planes on both side because while it includes all planes from those years, it doesn't include planes from 1944 and forth in first case and 1936-1941 in second.
For original campaign I included Stock_air.ini, it doesn't include any of the new planes but it offers all of the old one, unless you are trying to play campaign that does include new, WAW specific planes.
A thousand thanks for your contribution Chupacabras84! It's a worthy one .
Thanks dude, I am glad it is working for you.
