Apparently 50% is the actual minimum as established by the iMinDefense tags on the defensive buildings in the city. If the lowest iNoEntryDefenseLevel on a building constructed in the city is under the total minimum defense than the minimum defense should be considered the getMinimumDefenseLevel() (which is otherwise the lowest iNoEntryDefenseLevel amount). Therefore I'm a bit confused here... what text states that the city requires 25% or under to attack? Because I wouldn't be sure where that exact reference is being drawn from if the city's minimum is at 50% so I'd need to do some tracking down of how it's incorrectly drawing a 25% reference. Ok, so this still pointed out another very noteworthy issue in that you can continue to bombard the city once its at its minimum and that's not right. I'm making it so you can't continue to bombard the city once its reached its minimum defense %. ALSO: researched the bug you're claiming you're still getting with the Hunting Sight promo... it seems to be working fine for me. Remember that it will not be repaired on units that existed in the game before the fix was updated to the game's file set. Such units are doomed to experience the bug one way or another.
