There was philosophical debate on the question "if a tree falls in a forest and no one was around to hear it, did it make a sound ?". Obviously the answer to this question is yes, it made sound (the birds and the bees heard it ok).
On this point, in the mornings when your minions are up to no good with the women, you have the option to investigate, or not.
IF you investigate you get a bumper minion count and milk
IF you dont investigate, nothing happens.
But well, SOMETHING should happen. In this regard I deem the logic behind this event flawed and would suggest to alter this event whereby:
IF you investigate you should give a warning to your minions to behave with that girl (possibly kill some of your minions for being bold).
IF you DO NOT investigate, then you should really get a penalty notice at the end of the day, that your girl is exhausted, and will take like, a week, to recover, and that for the good of the hive you kill everyone involved (this is also a nifty way to manage minion count).
Finally, having discovered Aino via this game, I feel compelled to suggest an alternate picture when meeting her in the library:
Finally, all of the above is merely a fans suggestion, carry on regardless!
