Question for the devs about text editing

[LukeFF]

I have noticed that the "RO" text files (ROAmmo, ROEngine, etc.) can be edited, but in certain cases the game will overwrite these changes upon loading the game. In some cases it is the entire file (such as ROVehicles), and for others it's certain lines in the file. Before the new Steam file system was implemented we could edit any of the text to our heart's content. What changed with the file system, and will we ever be able to freely edit all of this text again?
