so back then i was asking if theres something conflicting the files within the 8 survivors and the super-horde mod, but for all things i have followed from the devs, theres no works and simply we finally realize to assume its the update's fault but... after a month from that question im back to find the solution for this so... i turn myself now..

i have been searching the sourcemod files finding the thing conflicting with the Script of Super-Horde and ironically its the Superversus Sourcemod addon itself that is conflicting the Super-horde mod

heres how i fixed it.

first go to Steam\steamapps\common\Left 4 Dead 2\left4dead2\cfg\sourcemod

find the l4d_superversus.cfg and open it

once opened, you will see a bunch of things that modifies the z_mobs try to reconfigure those

heres mine if you want to play it full horde mod

// Default: "100.0"
ci_background_mob_size "100.0"

// Sets the max mobs able to spawn.
// -
// Default: "150.0"
ci_common_mob_limit_size "200.0"

// Sets the mega mob size.
// -
// Default: "200.0"
ci_mega_mob_size "300.0"

// Sets the finale mob size.
// -
// Default: "250.0"
ci_mob_spawn_finale_size "250.0"

// Sets the max mob size.
// -
// Default: "100.0"
ci_mob_spawn_max_size "200.0"

// Sets the min mob size.
// -
// Default: "100.0"
ci_mob_spawn_min_size "100.0"

i hope this helps for the others finding a way to play super-hordes with the 8 survivors mod

edit: "but wait! this isnt a fix, this is rather a overwrite" yes it is just an overwrite but you can modify the superversus file in your will, basically you can just download the superhorde mod in Steamworkshop check the scripts file there named gamemodes and simply find every z_mob z_common things there, find their value and replace the superversus value with the z_mob and z_common value from the Super-Horde mod,

IMPORTANT NOTE: IT WILL DOUBLE THE AMOUNT THE SIZE OF THE PLACED VALUE WITHIN THE SUPER-VERSUS ADDON (basically if you put 200 it will become 400)
