Ok I looked around and found out that 2x speed doesn't affect Tech Points and stuff (I think...). But still that wouldn't explain why the tech points didn't advance at ALL or why the lagoon didnt go up in percentage.

Oh, and I actually did test around with my computer clock. It worked one time, made all my villagers Adept [whatevers] and finished building my hut (it was early on). I tried it again but it didn't work. Could that be what went wrong?
