Just to let you know that whilst using Vortex, and its created backup files in place, the game will still try and load the backup file. It is the only game that I am aware of that will try and load a file with the word "pak" within the file name and not just the extension. So, as an example........ alchemist_Globals_Creature+GCreatures Life 150+GCreatures Predators Danger Dangerous+GCreatures Predators .pak.vortex_backup the above file is a combined number of mods and whilst Vortex created it as a backup, which is fine, it still loads even though the extension has changed. On noting the above someone else tried the following..... The game still loads those PAKs. I just tested by renaming a quick start mod from Mod.pak to Mod.pak.off and because .pak occurs in the name, the game loads it. perhaps if the file name of the backed up files no longer contained the word "pak" they would be fine and not loaded. EDIT: Just to add.... If you delete the mod within Vortex it removes the pak file from the game BUT it leaves the created backup file there and so that backup file is still being loaded with the game. Thanks
