LtC sorry to hear, that sounds extremely frustrating.
I myself am nowhere near Astronomy. My Warriors managed to find 4 goody huts, which yielded 3 piles of gold and 1 useless map of the southern ocean. I stole an early Worker from Justinian with a Warrior, then came back with a Chariot for a second free Worker and a little pillage gold. A bit later I tried for an actual invasion with 6 Chariots, but that was 1 shy of enough to capture the capital due to some poor rolls. I settled for grabbing a secondary city and pillaging all his improvements.
On the domestic front, teching has been at a snail’s pace due to the reliance on slowly growing cottages. I build GLH in 1320BC, Stonehenge in 1080BC, and Oracle in 875BC (CoL). Had a bit of good luck when Confucianism spread to two cities automatically a turn or so after founding. My only GP so far was a Great Merchant, whom I burned on a trade mission for a measly 700 gold (in retrospect probably should have settled him).
Almost forgot events were on but sometime after 1000BC I finally hit one that gave me 50 free beakers for Calendar. Justinian also seems to have hit a research bonus event. Guess I am lucky not to have had some of those annoying slave revolts.
As of 1AD I have 8 cities (all but 1 coastal for GLH) and am about to finish Pyramids with 3 chops having just hooked up Stone. 19 techs are in including Currency and Calendar, no Alphabet yet. In 3 turns I am planning to hit Justinian again and hopefully capture all 3 of his usable cities. I’m planning to keep him around in hopes of scoring the final few points needed for a Great General and get a couple more free Workers and maybe an old tech or two. Researching MC now and hope to make it to Optics before my GM + conquest gold runs out.
