Prob won't happen. At very least even if will, there won't be flood. Cause of 2nd floor.
And to answer your previous comment along without spamming, get used to them, it's quite comfortable to play once you get used. But maybe i'm just adaptive or smth
P.S. there won't be flood bcs game will need to check constantly if player is in water to slow him down, same goes to other folk in schoolhouse
P.P.S. and it will lag the game, maybe
