Hello everyone,
yesterday I did something I regret. I went to bed and left my village of about 23 on 2x speed, and forgot to backup my save game files. I woke up this morning to find my village had been whittled down to 8, with 70% of them master scientists.
So what I did first was make some babies to get my population back up, and I then noticed I had loads and loads of tech points.I'm not sure what will benefit my villagers most, as I have level 3 farming and engineering, and level 2 of everything else. I have completed puzzles 1, 2, 3, 4, 5, 7, 9, 12, 13, and 16. I have about 150000 tech points.

I was wondering if I could take just a few seconds of your life to ask for advise of what tech to buy next?

150000! Nice you may have the level 3 of Science, then you'll get the tech points faster!!
I think if you were in 2x speed all the night, your villagers are much older now, maybe you'll need level 3 of Medicine very soon!!

Oh thank you!
I was contemplating science and medicine,And I think I'll get science first.

You're welcome! Good luck!
