I'd been planning a 100% speed run for a couple of weeks but with 0.15 so close I decided to just go for it. I managed to do it in 19 hours and 50 mins, finishing up with the 20 million green circuit achievement. This is a little more than 4 hours faster than the world record.

Sadly the replay breaks shortly after the first rocket launch. I think the "Game Finished" dialogue that pops up and requires clicking even in a replay resets some random seed and causes biters to react slightly differently after this point, leading to action desync.

You can watch the replay of this save (https://www.dropbox.com/s/4lq7szgqsac25 ... e.zip?dl=0) up to the Lazy Bastard rocket launch at 05:02 (with a train placed at 01:10). You can also play the save at the 19:50 mark. There is a train coming to end you, so get off the tracks immediately.

The 25k red circuit and 5k blue circuit per hour achievements can sort of be gleaned from production statistics. I can't prove the other small ones (golem, trees on fire, running over nests, 100 followers etc) without the working replay, but they were relatively simple to achieve.

I'm sad that I broke the record by such a margin but lack proper proof, but I'm proud of the process I used and figure it's worth a look.

My strategy involved placing relatively small and self contained miner/smelter/assembler setups using bots over every acceptable resource patch over a huge swathe of the map. All told I placed around 4300 electric miners and furnaces for the sole purpose of making green circuits. And of course the stupid amount of solar power required. The small size of each of the setups was key to maintaining a reasonable UPS. Even at the end I was maintaining 59 UPS.

Final build statistics: 20 million green circuits, 480 thousand steel, 256 thousand red circuits, 188 thousand batteries. Making 26,000 solar panels and 22,000 accumulators providing 1.5 GW of power. 133,000 yellow inserters, 12,000 efficiency modules, 9,000 logistics robots. Two rockets, one with a satellite and one with a goldfish.

Funnily enough I think sub 18 hours is absolutely doable with the same strategy. This was a very rough run and I spent a lot of time fumbling around figuring out what to do. I also made several small mistakes that probably cost me 30-40 minutes of finish time. With a known map and refined processes, 15-16 hour range seems feasible to me. No way in hell I'm doing this again though :)

How long in real time did it take you to do this? I assume that record attempts don't allow save/load, but do allow pausing.

Also, make sure to bug report the broken replay. Anything that breaks a replay probably also causes multiplayer desyncs since it means that two parties are not producing the same game state from the same inputs.

I did it a few hours at a time over the last few days. I work full-time and couldn't find an unbroken block of time that big if I wanted to. I'm not considering it a record for that reason, but it was fast enough that I wanted to share. I didn't pause to plan, only when I had to actually go and do something else.

And yep, bug is reported.
