I think these are not essential files, and I am not sure why I have them and not you. Some of these files where removed from the initial install, so they might have been leftovers from the development phase and thus not in use and obsolete. If you have no problems, then I guess there is no need for concern. People that are missing the others are not reporting any issues with it.

I see.
Thank you very very much again for your help.
I hope I won't have to make a new post in this forum again.

I've gone through the game again succesfully as a Rightful-Christian and every quest was O.K. this time.
There were a few crashes ("launcher.exe has stopped working") and 2 or 3 runtime errors during the whole campaign though but it was a tolerable amount.
Fortunately most crashes were on the campaign map and not during battles.
A little more work on it and it will be perfectly stable.
I have some crashes at other games too so may be it was just because of my system.

I'm playing as a Rightful/Old Faith believer now and when I was at "The Tale of Sir Gawain" quest, I chose to leave Iseult with the Green Knight again but "The Revenge of Sir Gawain" quest did not appear for the second straight time.
It would be fine if it was shown as an excluded quest but the question mark remained visible again like if this quest could appear in the future.
Now I know I can win the game without completing that quest but it's probably a bug or if it's not because "The revenge of Sir Gawain" quest is not supposed to show up (I don't know) then that quest should be shown as excluded.
So either way it is a bug after all and I encounter it for the second time!

I also noticed another minor bug.
There is a lady called "Dorothy" and among her traits there is "miraculous".
("her husband never gets injured during a battle or a quest")

Now...she married to Sir Dagonet because I wanted to ensure he never gets wounded again during a battle but it didn't help...he was wounded for 5 seasons after a battle so it is again a bug!

Sorry for my persistent posts but I would only like to help the developers to fix these bugs.

Hmm, I've just finished the campaign as a rightful/old faith beleiver and some of the last battles against the Unseelie Court, including the very last battle with the Grey Baron took place in "The Ever-Shifting Plains" map.
It is ridiculous...there are no plains in Bedegraine...it is a BUG again!

All battles should have taken place in a map which is in the Bedegraine forest!
Am I correct?

Ahhh shit,shit!
I've encountered another bug.
This time it is a major one and it is also related to a quest, "The Secrets of Merlin".
Near Norfolk where only women were accepted, I chose action 2. (preachers) and that was supposed to mean +1 christianity/season for 8 seasons to all provincies, BUT since then every province gets +4(!) christianity/season constantly and 50 seasons have passed already.
Every province is "Saint" now and I am "Sidhe" so there are tons of rebellions and I've noticed this just now on the chancellery screen.
Now I have to load the game to 50 seasons back because it would be extremeley tough to overcome this.
Ahh what a waste of time...

Hmm..and Cornwall still suffers -10 Millitary/season since "The Dragon's Heart" quest constantly...nice.
That quest was like 100 seasons ago....
I should check out the chancellery more often...

Finally, the developers responded me and since I can communicate with them in hungarian I could describe exactly what kind of issue I have experienced...so I reported them approximately 10 and they gave me their words that all of the issues I reported will be fixed in the net patch along with the ones that others reported.
So there will be a serious ammount of bug-fix in the next patch.
Thank God.

Hmm,hmm the new patch is not coming...now it would be time.
