and after I opened it, I altered the correct frag grenade to a bipd, then I saved, then I closed forge, then opened CE, resigned (no rehash required) slapped it back onto my hard drive, and it didn't work.
To be certain that I resign it properly, remember how Forge doesn't ask you for your ID's, so I was just doing it as a precautionary measure, although I have tried resigning it in forge, and the same thing happened with CE.
