whenever i attack a fortified castle or such with plague zombies being led by a Plague cultist, when they march on the walls and are killed by ranged attacks the game crashes this has happened twice now with attacking an empire desert castle and a temple of El when they die from a ranged attack the game crashes to desktop, im not sure if this is enough information.

what mods do you have active?

mostly the mods that overhaul the rituals for various factions and some class mods

I need to know the exact names of the mods you are using, giving me general random vague info does not help.

PAoD Illusionist
PAoD Necromancer
PAoD Demonoligist
insectoids
Engineer
Pretty Rapture
Zombie (patient Zero)
Blood and Horrors
War in Heaven
Disenchantment
Midget Mania
Earth and Sky
Fungal Fright
Lanka
Seeker
Ghoul Lord class
Dragon Fanatic Class
vampirelord
east and west
rot priest
lords of the desert

im playing this these mods in that save, ive started a new one with only patient zero but im being very unlucky with commanders popping up and haven't had a plague high cultist spawn yet

i just did a test with the zombie and did not encounter a crash so im to assume its a mod conflict as to which mod i dont know this sec
