I was telling my colleague that I was already translating the mod myself, I had it a bit paused (a mixture of laziness and things of life xD), and yesterday I got the right impulse to continue with it, when I saw this thread by chance, looking at the forum to see if there was any update of the mod before continuing.
So overall it saved me a lot of time hehe, he got confused because I suspect he used as a base the files that were already in the mod, which were very outdated, he wasn't understanding why you were telling him it wasn't right, for example, the setup.tra file weighed 4kbs when it currently weighs half that.
In general there were lines left over in several files and missing in others, it was a matter of checking and comparing file by file (translated and English), it took me a few hours but everything should be fine now.
