I appreciate the help, tom3kb. I have listed all rki mods, take a look at the second picture.

Thanks for your reply, R0adki11. I appreciate the help and currently I'm currently happy with the editor now (since there're tons of mods to test out) but yet I haven't found the problem. Take a look at these two screenshots:

As you can see I was trying to resume the very official campaign of the game (it does happen to all playable missions). I restarted the mission, save and resume immediately without exiting the game (ensuring no file/folder structure's been altered) but this error keep popping up. Then I tried to list all "rki_*" prefixed-files and found these (being used in game)

I tried to "trick" the game by cloning rki_backpacks.pbo and rename it to rki_base.pbo (just realized how stupid this is) but at no use, still that error. The remaining addons are the ones used in-game. Currently I'm living in the editor, trying every single piece of item just to feel how good this game is. Leaving the missions there (as well as tons of custom mission on Armaholic). I'd thank a million times if you could somehow take a deeper look at the error and help me solve it (I'm not dying to play, just take you time)
