No need for a prophet, it's the classic forum scheme seen so many times:
Noob: The game is bugged! I have made no mistake! And to make sure to get an answer, I create multiples threads about the same problem!
Veteran: Sorry but the game does not work according your preconceived opinions and wrong assumptions.
Noob: How dare you yadayadayadastartnamecallingyadayadayadatrolling
Veteran: I don't appreciate the attitude but I'll give you another chance.
See, your initial question was "The question now ist - because I cannot form the division - is there any way to resurrect the 23rd brigade?" and my answer was "I'm afraid that 'disband permanently' means just that - it's permanent."
And then about your idea "there's only savegame editing left" the answer was "savegame editing is not available".
I don't know how much more constructive assistance you require, but if you refuse to learn, next time don't bother to post a question here.
Apparently you cannot accept an answer that doesn't fit in your concept how the game should work, instead you started attacking me, nevertheless I have given you more constructive details, and then you started insulting me - dude, YOU have an attitude problem here, not me.
Too bad Alfred is not around anymore, he would have had a field day with you.
I wonder what happened to the green button of the old forum software?
