I have to actually disagree with it being a bug on nexons side. I thought so as well, because i got several enchant scrolls with no info on them. However when i traded my friend that doesnt mod, they were able to see it. So i switched over to my duplicate clean client (no mods) and sure enough all the enchant scrolls had all their info, and i was able to enchant them. With the mods i wasn't able to see nor enchant these new enchants. So it IS because of the mods. (test it out for yourself, any new gunner enchants will not work with mods, but will work without. You get 2 enchant scrolls after doing the basic gunner quests that will be blanked out if you mod, try running clean and see if you can see them).
