the 'nutella.nif' has nothing to do with the latest game updates. i've checked the files, and nothing goes wrong with the nif file. no new weapon after the update needs to assign with the file. its just a sniper mantis remake to works with the chams and ZBuffer for the game. should be has to do something with that totalitem.bsv files. something that blocks or prevents the nutella to initialize
you know how to edit the .bsv? someone said use C++ to edit it, but when i google.. bluespec verilog is the thing that can be use to edit bsv file.
