A jumbled sentence which explains nothing about what the mod you're looking for is about, other than "r12" (which may be the mod's version number or the mod engine's version number,) is as far from "details" as the Earth is to Alpha Centauri.
R### is a standard thing in programming, the R stands for "Release", as in, a counter for the number of updates released - it doesn't always agree with version number: the in-game version number can be 1.18.1, for example, but being the 28th version of the game released, it would be "R28."
