To those who wonder how to fix the mod from spawning ginormous Dusk Landbats:

-go to Forgotten Construction Set

-uncheck all beside this mod

-go to "changes"

-search Dusk Landbat swarm that has "SQUAD_TEMPLATE" on them > click it

-change the end of the line of Dusk Landbat on "animals" panel from:
12 22 "700"
to
12 22 "100"

-after that save the mod and then import your game.

(it seems like Shiroho made an error on the percentage while making the mod, welp nobody's perfect i guess, thank you for making this mod!)

if you want a patch instead of this feel free to message me, cheers!
