halo trial pc sparkedit help

[Dictator]

hey everybody i have a problem. i have both of the ppf patches to be able to use the trial map in sparkedit. ok heres my problem... i took bloodgulch and duplicated vehicles around one of the bases and i made the banshee that was on top of the base and made it a hog. after all that i clicked file then save changes. i applied the undo sparkify patch and i opened bloodgulch in the acutal game. when i went to the same base i edited half the vehicles i duplicated werent there and the banshee on the base that i made into a hog wasnt there, there was nothing on the base. did i do something wrong?
