Small update...
I've been tinkering with a lot of events and the resource/IC balance, and I'm not yet happy with where we are. Too many countries had too few resources to feed their IC, and I've made some crudely effective alterations to this. Darksoul and I are also working on problems regarding ESE for "continent states" like the Draka, US, Germany, etc. that arose in 1.04.
As it is, the game will run until at least 1961 without a crash, but none of the powers will invade Japan. However, the 42 scenario runs fine until Germany is annexed, and then will CTD. As it is, we need some serious balance tweaking, the Draka AI will nearly always attack Germany through Italy and Bulgaria rather than strictly through the Caucasus, and no country under any circumstances makes a landing in Japan's home islands. Draka infantry runs way, way too quick across Europe for the size of the German forces involved, and this needs some work on both sides.
That's the progress report, we are making strides, but every issue fixed seems to bring on two or three new ones.
