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.

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

Using the same random seed is the easiest explanation.

this is a big fail for this game and i don't think the problem is the lack of random..
one of those games in the link, (32629852) and (31835798), have been played three weeks after the other one..

Well, that's pretty interesting. Both teams are however bots. Is there a difference in bot team processing?

Yes and then it is a bug in game engine design, which is even worse than just a bug in one line of code, i think.

Talking about numbers and pseudo-random does not make sense.....
My calculator generates pseudo-random numbers, and they are never the same.
The engine numbers are generated BB, for example, 0.87 .... 0.65 .... 0.43 .... 0.13 ... 0.99
In the next game the same teams will be generated the same counts in the same order:)
Do you know what are the chances?
It's impossible
