No Nolan, there is a big differnce here.
1. The problem in china is due to lag and the province not being reconisgned as Japans after being conqered, so this is a bug or a lag issue.
2. Major simply clicked a wrong button for th even while clicking other pop ups. If i had a save we would just simple reload.
3. The problem with with the supplies in Europe is not a bug or lag issue or click of a wrong button. The player was warned about supply issues with minors taking over areas, by yourself and major, and this is what occured. It is not a bug, or a lag problem. A simple in game fix is to send belgium lots of supplies and oil and let them fix it, there capital should relocate back to europe so should not be an issue as no Convoys involved. This is exactly what my problem as been in russia, alway having to send supplies to my minors to supply the whole southern Russia.
The reason this happened is becuase i puppeted Poland, you would think supplies would simply pass through poland wouldnt you, but no. But it was my choice to do this so i didnt complain. Same for anyone else, if you choise to invade somewhere or move into the wrong areas and lands change to another nation tough luck, it was your choice and not a game bug, simple a lack of experience or knowledge on how the game mechanics work. Im sure they wouldnt repeat the same mistake and a good lesson learned.
This is the way the supply system in HOI 2 works normaly works well but from time to time there are probs that are fully avoidable. It may be fixed in a patch but i doubt it, it is hardcoded into the game and here to stay.
So unless it is a bug or caused by lag issues or an honest error then no reloads or edits. You will note I have never edited before and am hesitant to edit any game, as were does it end.
So as this mistake was invading the wrong areas and then moving units and these areas spreading to a minor there will be NO edit or playing of that nation. It was a players choice and wrong strategy that casued this.Send them supplies and what ever they need, is far easyier fix. I have offered a solution to you nolan so that there is no huge loss to the allies as it was an error, but by right i can destroy all your forces there and should really but im being nice. Take the offer while you can as it wont last long.
Also you wont get liberation event unless the land is UK or US, so you need to redo invasion anyhow.
