First and foremost, thank you Lifthrasir and Jurand of Cracow for updating this wonderful mod with so many great and immersive changes. It is truly a joy to play the game with it.
Now, like others mentioned before, I've had issues with a few traits that have negatively affected my experience, specially the Intelligent trait. I am ruling over a nation of ignoramuses, where stupidity is the norm and every general coming of age is retarded or autist and no amount of schooling can fix it. It would be pretty hilarious if it wasn't me suffering the consequences.
Reading Jurand's comments of a new incoming patch is wonderful news (thanks Jurand), however I didn't know about any of this since I've been without internet for a while. So, frustrated with my generals and without access to the internet for help, I decided to take a look at the mod and fixed some the problems I encountered. I will post them here for those of you in the middle of a campaign, since I read that the incoming patch is not save game compatible.
The bugs were very simple to fix, I simply followed the errors in the log file. Most were related to trait levels not being specified int the vnv.txt file -this was the cause of the "teenager" trait disappearing. In the case of the Intelligent trait however, I took the liberty of going beyond bug fixing, as I felt the setup was a little biased toward stupidity. With my changes, after a general receives at least a basic education, he will no longer be ignorant.
(Please note that I use Linux and edited the files with a Linux text editor this should cause no problem, Windows is the odd one that uses carriage return characters as newlines instead of the established /n character but it also recognizes standard newlines)
Jurand, I saw somewhat more serious errors about the settlementExists condition not being usable with the ComesOfAge trigger. If this is the case, you might want to rework all these triggers because this section of code will not work. I had the logs ready to send them to you but I seem to have lost them
Edit 1: to my previous post: Please do not forget to DELETE all the string.bin files in your text folder to force the game to recreate the vnv.txt file. Your game will crash if you don't. All the files have to be deleted apparently; at first I deleted only vnv.string.bin and the game didn't crash on startup but it did at the end of the turn. I had to fight a battle again after I'd had a heroic victory against a superior Polish force. Wouldn't want that to happen to you.
Edit 2: All my changes can be found by searching for "mm_fix", in case anyone is curious or wants to make changes of their own.
