why does whenever my game change level,my saving function always failed?

I think you mean the loading of the previously saved game?

because the order and/or structure of the saved game changes with the level entites.

loading a saved game only works with exactly the level you saved it.

that's even my problem too sir, everytime that im in the level 2 of my game.whenever i try to save it, a malfuction will pop-out saying."saving error".and when i try to load my game in the level 2."load error"

hmm, and what settings are of your saving? SV_VARS, SV_INFO etc..?

i use SV_ALL-SV_PHYSICS sir...

hmma, i think that save all and is your problem, but i never have problems with that.. try all and maybe you'll find what is wrong
