So I've noticed a new "trend" here during this new war, and apparently its the new way to hide alliances banks.
Here's how this works:
Nation A declares a war against Nation B. Right after declaring the war, Nation A will drop his AA that he was on. Nation A will then create a new AA, and Nation B will still be fighting Nation A, and his first AA, even though Nation A is now on this brand new AA. When the war is complete, and if Nation B wins, the loss goes against Nation A's original AA, not the one he ended up on.
Typically this person had switched AA's right before declaring war, and usually switch back to their original AA after the war declaration.
I would like to suggest two possible solutions to this.
1. Do not allow nations to do this at all. Make the leaving of an Alliance Affiliation not available, until the nation is at peace, in all wars.
2. If the above won't work for some reason, then when a nation has a blockade put against it during a war, the bloackaded person shouldn't be able to switch AA's.
