I've tried to duplicate it, but the conditions may be dependent on what the computer does that turn. One common event seems to be that this occurs when allied CAs show up. GeneralChaos can chime in, but it might also correlate with no IJN air support (I didn't have any on my invasion failure). So part of the condition could be no IJN carriers and allied CA presence.

I don't think it needs to be Leyte. In my instance, it was Tarawa.

So, we shouldn't just be looking for a successful first turn invasion of these islands, but a successful first turn invasion without IJN carrier support and with the presence of allied CAs.
