something reeeeeeally weird happened

[Sky]

So, as you know, i'm playing the "every class/race combination" challenge thing.
I'm now playing a Half-Orc Mage; i've just now finished playing my Half-Orc Ranger. These two characters have been started and played at the same time, i just focused more on the ranger.

Now ..

They both have the same randart set.

I did not do this on purpose (nor do i know if there is a way to do this), so, there are two possibilities:

1. a one-chance on 999999999 has happened and both characters rolled the same exact artifact seed

2. a bug

i can provide files of the mage, but the ranger is gone, unfortunately.

That is super weird. Both possibilities seem very unlikely. It's just possible that if you start one game from a dead character, and then start another game from the same dead character before you save the first game, that you might get the same randart seed, but I haven't checked.

[klassik]

does the game still ask if you want to keep same randart set from last time you used save file?

is it an option?

[Sky]

that was something that 3.x had, but 4.x doesnt.

Once upon a time I used to save scum quite heavily (I've changed, man). Once I bought a scroll of acquirement from the black market. I used it in town immediately and got something like Farmer Maggot might drop. I repeated and I got exactly the same item. I used WoR and tried the scroll deep in the dungeon and got something else but not very useful. I soon realised that the item I would receive would be exactly the same if I hit precisely the same keys before reading the scroll. If I moved even one space further then I got a different item. I played around with this mechanic for a while.

If it's random, it's random in a sense I don't quite understand.

Anybody else ever found this?

Anybody else ever found this?

still works like that.

What happens is that the random number generator state is saved when you save the game, so when you load the save getting the RNG to generate e.g. the the numbers to create an item from ?acquirement generates the same item. If you rest or take a step then the game has to roll some extra numbers (for example, should it create a wandering monster that turn) and this moves the RNG on so reading the scroll now gives you a different item

Storing the RNG state is entirely intentional, the thing with acquirement just allows that to be seen quite clearly
