i have the impression that the number of possible simulations is far to low (i mean the "random" sequences from which the probabilities of all events are based on).
I.e. this 2 games of mine this season seem to have the same simulation: (29614949), (29614903).
Down by 20 or so in first quarter, almost no OR in the first half and then my comeback in the second half, with final victory (in one case even despite an injury). In fact, when the second game I saw that I was losing so bad in the first quarter, I understood I would have eventually won.
Maybe the BBs should do something about it as well.

Hard to imagine what kind of software bugs could be related to these "identical games". (earlier commented by BB)

I also believe, unfortunately, that there is not so much random in these simulations. Pure calculation based on player skills, game shapes, enthusiasm...

Is there someone who could confirm that there is a random in simulation?
You should have two consecutive games in the same week (no updates between) against same opponent - both same tactics and same players..... I think also enthusiasm should be normalized for both teams.
So if there are such games with different simulation, I would be glad to see those....

We will be looking into the problem. I'll let you know as soon as we have an explanation.

Another one: (30222352) and (32539111). It does not affect me, but just thinking it could hapens to me...

It's no bug.
It's the lack of random variables in the match engine.

BB game engine is the best I've ever seen
but now I understand why it is so well balanced
match result is the result of equation (without random)
match live is only the creation of an exciting story, whose end is known at the start
but everyone can live illusions
this is better:)
greetings

If you are interested, read about random seeds and pseudorandom numbers. Moutlinho has already talked about it. Random isn't strictly true random, we can't recreate random. We don't even know if random exists, everything is the result of causes, forces. When we don't understand the causes... it's random or magic or from heaven.

If the same random seed was used for both games, the same pseudorandom numbers were generated leading to the same outcome. It was random, as random as for any other game in BB or in other online games probably but the same random for both games.
I actually don't know what I am talking about, please correct my nonsenses moutlinho :)

I can figure identical games played during the same training week but played 3 weeks apart now that's troubling :(

I'm amused by the fact that although the stats are *exactly* the same, the PP100 for the Φοινικας Καλλιπολης Center was better in 324 compared to 303.

Indeed. I think what we are seeing here is the same teams, same lineups, and same tactics, with all other differences (in this case only player experience and team enthusiasm, since the games were played with identical gameshape and skills) so small that the games happen to run the same given the same random seed. There is a tiny difference however, which I guess could have changed the outcome at some point. This difference is shown by the rounding of the PP100 figure. Another explanation for it would IMO be a bug in the rounding, which is highly unlikely.

I seem to remember the random seed issue was fixed when people were seeing identical games the last time. Is this not the case then? I think this should be a pretty high priority.

Using the same random seed is the easiest explanation.
