Trait and Sea-side Rout Problem

[soibean]

Playing as the Macedonians, I receive the trait decrease for Occasional Drinker about every single turn during my campaign. Ive never had this happen before, but it pops up even when my generals dont have the occasional drinker trait

Macedonians vs. Greeks at Mytilene (sp?) I forced the enemy to rout, and instead of running back towards land they all ran into the water and drowned. Dont know if this happens all the time but... common sense now soldiers.

one last thing, is there anyway to allow for a catapult or ram to attack a damaged wall? I hate attacking a city with damaged walls and for whatever reason my iege equipment can't target it
