well, unfortunately had the same issue with Mavs, but if this mod you're linking is different/updated from the one I downloaded in the OP of this thread, it's certainly worth another shot.
EDIT: Well, I'm a complete idiot! that version works beautifully, and without any ill affects to any modules thus far. Tested out all types of Mavs on both the F-16 and F/A-18, and everything seems fine. Thank you so much for linking me that, I don't know why it never occurred to me to check if there were more recent iterations on the mod, but at least everything's functional now. Massively appreciated. It's going to be fun to test out the KEPDs.
