Hope this is the correct venue:
I, too, have had a problem with a tropical Spitfire. Testing of the "Darwin Spitfire" campaign went well yesterday, but since installing Part 20 this morning, the first campaign mission refuses to load. The briefing page appears, but the "arming" button, for placing the proper skin, now goes nowhere. I clicked "Fly" anyway, to see what would happen. After winding up to 100%, the loading window says: "Error - Misson loading failed: null."
Having never attempted to properly post a portion of a logfile before, I'm somewhat hesitant about this but - here goes. Fimgers crossed, and I hope these lines are relevant:

Could someone please advise regarding not only the problem itself, but the proper place for posting such an inquiry? Thanks to SAS for your patience.
