Any chance you'd be willing to change the name of the file "greenenergybladeparticles" both normal and 2. Along with the corresponding files linking to those files? The reasoning behind this is due to the factor the FU already has a file named the exact same thing (only with the green one). This is causing a conflict with both the weapon and another mod that I have called "Immersive Props" that uses that file as a dependency. owo Edit: After getting that one fixed I then started up the game again just to encounter another error regarding "mechainfusion"... that one is a little beyond my understanding to solve. So further testing has came to a halt for me, idk if you use FU or anything, but do you have any idea if it is actually compatible and it is just me, or you simply don't use FU so you didn't make this race with FU in mind.
