In one of my mods the game crashes for an extremely weird reason. -I have a catapult with 3xp (lvl 2) and City Raider I promotion -This catapult attacks a city on a custom map -I have researched 50% of the tech tree I have made yet -This doesn't happen in the early game, catapults with all characteristics mentioned here can attack cities fine during the early game -The catapult can attack other units fine -I can conquer the city with other units -Happens with many cities accross the map -Catapult without promotion can attack city without crashing That problem isn't the only one. When I'm progressing to 235 AD, it also crashes. I can reach the year 235, but the game then crashes the my turn is complete. Anyone get some advice? I really need to solve this, or I might quit modding alltogether.
