If you do enough looting, hitting every toilet and liquor pile you find, then yeah, I bet you could find around 54 bottles of murky water by then. The problem I'm referring to is the one TFP literally told us themselves. I'm not making problems up here, like you seem to believe.
As for ignoring realism, what I'm referring to is, if there's something realistic they could add that would be beneficial to players, they say they won't add it (example, players crawling through 1 block high spaces). But if it's something realistic that is detrimental to the player (ridiculously high vehicle damage from hitting something in a vehicle), then they're all for adding it.
