CraftingStationRange for Valheim lets you remove or customize the range limit of crafting stations. Change the default 20 range individually for the workbench, forge, stonecutter, and artisan table.
Set the value to 0 for unlimited range (stations still need to be loaded by the game). Install via BepInEx, drop CraftingStationRange.dll into BepInEx/plugins, then tweak the generated config file in BepInEx/config. 🔧
