It's what I had to end up doing. No it isn't curses fault fast isn't a part of curse. That launcher doesn't have the ability to add any mods that aren't signed up. I understand that it goes against what I think curse was supposed to do to help devs. It is apart of the dw20 though. Wish that could be a part of the mf3 mod pack or really any self made pack being that any pack gets unplayable if fastcraft isn't added. If I have to add the mod manually, why have the curse middle man? Obviously this is an exceptional case because of how heavily relied upon fastcraft is to everything atm.
