The archive isnt needed since the game is on Mossy's itch account.
Ok, good to know!
May I ask which Kit to Leader V5 you have? If it's the anniversary edition, that's the one on mossy's profile and we don't need that one
It's a version from around 2020-early 2021, since that's when I used that account mainly.
You'll have to talk to Mossy directly - I suggest on Discord but he does have links on his main profile directly to his accounts where you can talk to him.
