I'm only getting the diastrous ones it seems:

last night, after they had been working for hours and hours and hours on getting enough tech for 3rd level science along came the
obnoxious parrot
some "unfriendly" animal that kept bothering my scientist at the table so much that they lost a total of unbelievable 33.119 tech points. I just managed to get the 150000 a minute ago.

And then about half an hour ago the flood from the waterfall diminished my food to 750 - and I was so happy it had risend above 2000 for the first time.

thanks a bunch i've had my share of events so far
