So seem to keep happening when I defend a city with no wall from costal siege.
I took over Sicily and Cartage declare war on me via scripts.
They would almost always attack AKRAGAS, a unwalled costal town.


Faction: Rome
Turn: 28
City: AKRAGAS
YEAR: 272 BC

Bug: Attacker would converge to a weird spot next to city center.
Any unit that walk into that spot get caught in it, they get stuck in "match combat".
I did a "Debug" camera and it seem there's unit "UNDER" the map that suppose to be on the boat.
Some enemy unit that debark boat would run pass my defense and suicide to get to that spot often breaking into my defensive formation and refusing to route if they are elite unit.
