I would like game presets in game setup. Then you know all intended settings are fine according to the selected preset. It is sometimes surprising which settings in background were set to default and which one stayed on the value  of last game. Different in multiplayer and single player game setup. Best surprise is after a 4 v4 game switching to a 1v1 which is won in second 1 due to both players being in team 1 (happens to me up to one every half of the year, forgotten about that) 

Oh, so you choose random as placement - I understand now. I think it would be a hard to delay the random selection to the mapgen script. One would also have to change replay-summary: there it shouldn't be displayed as "random". The more complete solution is the one stated in the ticket.

Most of them lived after AD 1, which I'm not a fan of, but fine. The only one who's definitely too late is Ballomar, since he lived in the second century AD, so I wouldn't include him. @manowar If you make those changes to the PR, I'll merge it.

Thanks @Frederick_1 that provides useful reference points for any future challenges / changes.  

Oh, "someone" had a similar experience... #8148 seems to me like a different case, as one deliberately sets up a specific match versus playing a random random random game. So, the above message is the intended behavior when player settings and rng result aren't compatible? Could the game be forced to comply with the settings so that an error won't be shown to the player?
