FYI - the case is settled, as the player admitted to auto-queuing. Also, further analysis of commands.txt showed that he had more than 3x the # of commands given as the second best players, including 28 separate attack commands against 28 separate targets in a single turn. His game is as natural as the average Youtube fitness influencer.

Also when materials or simulation templates were changed. I'll take a look at the issue.

Yes it is although even the map is broken I think. "Strategic Campaign ..." under Skirmish maps.

These kinds of challenges are what would be interesting to have as Achievements. But, as some pointed out, just pushing for 100 pop would hurt the late game, so most Achievements could aim at improving that, with extreme ones only possible to be achieved with certain civ/scenario combinations.

Installing Firefox solved my problem. Thank you all for the replies!
