fallout3 Fallout 3 Colonel Autumn glitch in Vault 87

[KillerJekoStar]

Hello everyone,
i have this problem that keeps popping up every time i get to the end of the "Garden of Eden" mission, i get hit by the grenade, the two soldiers appear, the colonel appears, but the asshole does a moonwalk and disappears into the other room without talking to me. i tried everything, setstage, clicking "E" and the left mouse button when they talk, but nothing... does anyone have a way to force the next mission to start (in the enclave base) or a mod, a patch, a fix that can fix this problem? HELP!
