Well, for next time I have DRM-free copy from Humble Bundle so it should be, probably, some different code.

Oh ok :)
I hope it will be flawless then ;)

I managed to finish the game with the Atari executable, everything worked fine both Upper Hadar and the Necromancy skill

Okay, I'll use it if I encounter an issue then :)
Thanks for your feedback !

Nop.

I found the thread through internet search, found it quite strange couldn't talk to some NPC but thhought it could be some random quest...
After found Lina's fountain, spent 1/2 hour trying to get around why wont work, had to resort to internet...

Don't know wich version I'm playing but it's the last one since I installed the game a couple of months ago.

Thanks for the help in 2019. Cheers :D

Yoo, I was reading about this topic since I had this same bugg. I have KB TL bought on steam. I had showflyingdeath first set to 0(automatically?). This is my third time playing this game and its the first time encountering this bugg. Normally I would see damage in the yellow ish color and the death amount in red(both at the same time but not at the same place in the screen) so basically it was working perfectlty. But now fort some reason it only showed damage before and I managed to change showflyingdeath to 1 but can not change it to 2 for some reason? When I start the game it changes it back to 1. I saw Lexor being online so i decided to ask even after 9 years XD. I just wondered if you still remember what you did to fix this bugg.

From what I read in my first post value of 2 is a buggy one, so it's good for you to not be able to set it.

Google translate:
I wrote to the 1C publisher by mail a week ago about the errors of the "upper Hadar", and the publisher replied that the developer had sent an update that fixes the errors. Therefore, the game should already be updated and the bugs will be fixed. The game must be updated to version 1.7.35.398.

1C asks me if the errors are fixed, and I have to send them an answer. Bugs fixed?

I'm rather not going to install KB again, but:

1) As I can see the last update for this game on GOG is from October 11, 2017.

2) Here is the post from October 16, 2019 (two years later):

Unfortunately I can't test it out as the offline installers have not yet been updated (I don't use Galaxy) - support said that it should be "available soon". I'm looking forward to another play through so when GOG do upload the new installers I'll check it out.

Thanks for the answer. I hope the bugs have been fixed and there will be no more problems. It's strange that it was only fixed after my complaint. It seems that no one has written to them about this error.

the offline installer for windows (eng) has been updated to 1.7.35.398

unfortunately I will not be able to test the proposed fix for a while, as I do not have any savegame

I have just started playing the game and not gotten to upper Hadar yet, but as of 2022, the garrison bug still persists.
EDIT: Got further down the game, garrison is the only bug I encountered (other than typos and some false tooltip texts). Hadar is fine, necromancy skill works as it should.

Thanks for the information. I will try to write about the errors to the technical support service of the publisher "1C Entertainment".

Welp, it would appear the bugs aren't fixed at all, as after playing for many hours per day for many days all saves excepting my very first autosave were lost meaning all progress was lost or reset to zero. Unfortunate.
