The airfields are included in the Crimea41.rds file. Instructions can be found inside this (old) document by Lonestar.

Generally when this happens (but not always), it means that one of the folders that DCG accesses is read only. Make sure that your DCG folder and all subfolders and files in them are NOT read-only. Also, make sure the main IL-2 folder, subfolders and the files there are not read-only as DCG must write to them (and it makes a back up copy of DGEN and NGEN as it over-writes these).

The download still works, but only for build #21, which is five posts up.

That's a good question. I don't remember, but I'm guessing no. You could simulate it by skipping a few days, which you could do while on the debrief screen. While on that screen, tab out of the game and run DCG, go to the General Campaign Settings and change the "Time Passage" to "Fast". Tab back into the game and generate the next mission. It'll skip a few days. Just remember before the next mission generates to set the "Time Passage" back to "Normal". (Or whatever setting you like to use.)

There is an option to not have them reset on a KIA or MIA.

That's strange. I'm fairly certain your timetable as shown should work. And if it doesn't, I must have introduced a bug. I'll have a look and get back to you in a day or two.

I can certainly add a timetable command to transfer ships from a srd to a prd. Should be a simple addition (famous last words). I'm not sure I follow your second request. Transferring from a carrier on a srd to a land base or to another carrier in that srd? Or a carrier in a prd? Transfers are limited by the number of squadrons already based on an airfield/carrier as well as the distance (restricted to being within the range of the planes and the "action radius").

Of course. I should have thought of that. (I really should add a routine to see if it's already running and warn the user if it is.) Glad you figured it out.

DCG will actually back up DGEN and then overwrite it with DCG. So it doesn't matter what DGEN you have installed. I suggest that you try a "vanilla" DCG campaign or two (I don't know if Shakkaali's are up to date). To test, a German or Soviet campaign is probably the safest.

What campaign(s) have you attempted to create? And are they offline or online? The log is showing that no campaign has been selected (it's as if you've run DCG for the first time).

I don't follow the development of BAT, but perhaps the most recent version has added some items which have messed things up...? Maybe someone with more knowledge of BAT and DCG will chime in. In the meantime, you could post the error file. Even if that error is gone, there may be a hint of what else is going on.

Looks like an error with the Class.DCG file which was designed for the mod. "None" is not an acceptable value. "none" is. (No caps).

Check to see if both the IL-2 folder and all its subfolders are NOT read-only. And also the DCG folder and subfolders. If all of them aren't read-only, set them to read-only and try again. And if that doesn't work, please upload/post the dcgerror.txt file here for me to see. Thanks.

Does it still generate the mission? (Even if you have to alt+tab back into the game.)

DCG will default to IL-2 1946, but you may still be able to play the original IL-2. There is an old setting to select which version of IL-2 that you are using. Run DCG and once you get through all the selection, you should be able to go to the menu FILES -> SET GAME VERSION. Hopefully that will make it stop popping up like that. (But I can't promise that DCG will work flawlessly with the original game as so much has changed over the years.
