You should be able to replicate with the following:
generate a new world on a fresh game (as in, no modifications made to the configs on any mod).
copy the default generated "tinkersurvival-server.toml" file in the "serverconfig" folder
paste it in the "defaultconfigs" folder.
modify the item=[] config to:
["hammer-immersiveengineering:hammer", "wirecutter-immersiveengineering:wirecutter", "pickaxe-botania:manasteel_pick", "trident-minecraft:trident", "sword-minecraft:wooden_sword", "shovel-minecraft:wooden_shovel", "pickaxe-minecraft:wooden_pickaxe", "axe-minecraft:wooden_axe", "hoe-minecraft:wooden_hoe", "sword-minecraft:stone_sword", "shovel-minecraft:stone_shovel", "pickaxe-minecraft:stone_pickaxe", "axe-minecraft:stone_axe", "pickaxe-minecraft:iron_pickaxe", "shovel-minecraft:iron_shovel", "sword-minecraft:iron_sword", "hoe-minecraft:golden_hoe", "axe-minecraft:golden_axe", "shovel-minecraft:golden_shovel", "pickaxe-minecraft:golden_pickaxe", "sword-minecraft:golden_sword", "hoe-minecraft:stone_hoe", "axe-minecraft:iron_axe", "hoe-minecraft:iron_hoe", "sword-minecraft:diamond_sword", "shovel-minecraft:diamond_shovel", "pickaxe-minecraft:diamond_pickaxe", "axe-minecraft:diamond_axe", "hoe-minecraft:diamond_hoe", "sword-minecraft:netherite_sword", "shovel-minecraft:netherite_shovel", "hoe-minecraft:netherite_hoe", "axe-minecraft:netherite_axe", "pickaxe-minecraft:netherite_pickaxe"]
