Random civs on custom games always end up mirroring each other

:arrow_forward: ISSUE EXPERIENCED.

I have played 1v1 with my friend today and we both picked random civs. However this caused the game to always end up with selecting the same civ for both of us!!

:arrow_forward: FREQUENCY OF ISSUE

:question: How often does the issue occur? CHOSE ONE; DELETE THE REST.

  • 100% of the time / matches I play (ALWAYS)

:arrow_forward: REPRODUCTION STEPS

:question: List the DETAILED STEPS we can take to reproduce the issue… Be descriptive!

Here’s the steps to reproduce the issue:

  1. Start a custom game and invite a friend.
  2. Have both you and your friend selecting random civs.
    3.The game will then pick the same civ for you and the opponent resulting in a mirror game

:arrow_forward: EXPECTED RESULT

Civs should be random however I would expect the game to pick a civ that is different from my opponent most of the times

:arrow_forward: ACTUAL RESULT

Game always picks the same civ for me as it picks for my opponent which results on us always playing mirror games. Example: Spain vs Spain, French vs French, etc.

:arrow_forward: GAME FILES

:question: Include a OneDrive or Google Drive link to a SAVE GAME or REPLAY FILE (.aoe2record) of the match where you encountered the issue.

:arrow_forward: IMAGE & ATTACHMENTS

:question: Attach a relevant PICTURE (.jpg, .png, .gif), VIDEO (.mp4, YouTube), DXDIAG FILE (.txt), or CRASH/GAME LOGS (.aoe2record, .txt) below.


How many matches did you play? Could be a coincidence.

It happened 4 times in a row

It happens to me too when playing 2v2 with my friend in the same team, both choosing random civ. The rate of picking the same civ is unusually high. However I didn’t record before, will provide some information after.


ok I played 5 2v2 lobby games with random civ with my friend today. The setting is same as the screenshot.

The result are as follows:
France + Spain
Double Sweden
Double Portuguese
Double Dutch

And I tried restart the game and played the last one:

Haus + Chinese

It is the same as my impression: the random system will pick the same civ since the second game. It seems there is a bug exists until one of the mate restarts. Devs can you please check? Thanks.


Thank you for the reports and to @Leafy6224 for the extensive testing! I’ve added all of these notes into a ticket for the team to investigate!

Thanks again!


Thanks for the response!! I really appreciateit!!

  1. We have 16 different civ so both of you and your mate have 1/16 to rdmly pick a civ

  2. 1/16 * 1/16 = 1/256 to rdmly pick a couple of civ

  3. 16 couple of civ are twin so 16/256 = 0.0625 (and 0.9375 are not)

  4. In your situation, you played 5 games, 3 was with twin civ and 2 wasn’t and
    the proba of one combinaison is (0.9375 ^ 2) * (0.0625 ^ 3) = 0.0002145767

  5. There are 10 possible combinaison (C(5_3) = 10) so the probability of finding 3 twin civ in 5 test is
    If i am not wrong ^^

Yes and there is only 3 possible situations for 3 continuous double civ so it can be 0.0006437301.
