I have noticed that late in the war when the Japanese resource level goes to zero that from that point on, no matter what the resource level, nothing seems to get produced anymore.
Basically, when playing the 1944 campaigns (Marianas) as Japan vs Computer opponent I wanted to check the 0 resource level bug to see if it got fixed and it did. However, then I put all my MCS back into port at Nagoya and noticed that I was no longer building aircraft -- outside of 1 per turn per model. I switched the setup to both Human and set all air groups to not take any action in a turn, pulled all Allied subs away and counted the aircraft deployed and in the pools for select Japanese production models and the number never changed, irrespective of the Japanese resource level. This can't be right?
