Early war, you could easily miss traffic in the Luzon Straits, since you don't have radar, but Makassar Strait is much narrower, and should be relatively easy to find traffic in, especially after 10-11 January and the battles for Tarakan and Balikpapan... You should find invasion forces during and after that time, and then eventually merchant traffic as the year progresses. Use JSGME and do an "Export active mods list" D-Jones, and then post that here. Also, did you delete the Save folder or use MultiSH4 to make a new one after activating the mod list you have?
