Jesus3747 The issue is that the Particles fodler is called particles, you need some random numbers, or another kind of indiviualization at the end so the particle folder does not count as "duplicate" anymore, it was one of the issues I found with the early mod upgrader, Walt fixed it by attaching what seems to be a random number generator to the upgrader which adds numbers to the particle folder ( and inside the mod.txt to make them fit together) so the engine acknoweldges it as a seperate folder.
