MartinCoetzee that's totally not normal, as I myself am constantly changing some weapon stats in the mods I have installed and I still have 0 problems with it, even though I'm really a noob in the coding language, for example before updating the microtech mod I also wanted a powerfull(and basically unlimited) little reactor with a 1x1 size, so I changed the stats of the small reactor in the ABH mod in order to make it spawn 5 energies/0.1 sec and it worked perfectly fine
Only reason I could see for your modifications not working is that you don't change the right things, or change more than you're supposed to
I would suggest that you post an example of a modification attempt you made so I could tell you what's wrong
But also in your first message you're talking about the names in the files and stuff, If you have to change the strings, it's really that you're doing something wrong somehow, because changing some numbers in the stats of some parts doesn't interact in any way with the strings in the mod
