HaloMods "Classic" Read-only Archive

hey, im kinda a noob at modding but i did something wrong today. when we were trying to make shotguns launch wraith mortars, we went into H2edit and made the hex code thing the same as the wraith mortar. well, it made every shotgun turn into the top of a wraith and when i try to go back into ch2r or H2edit and click on shotgun, it freezes. also, can someone give me a proper tutorial on how to make the shotgun launch wraith mortars?

please help!

EDIT: fixed the shotgun problem by making backup maps off of the original disk, but im still looking for a tutorial on how to shotgun>wraithmortar
