Edited equipment files being overwritten on game start

[Hybris51129]

So I have been getting back to toying with BattleTech and also experimenting with RogueTech but something that has dogged me for both versions of the game keeps popping up.

 

 

So for example I edit the stats on a double heat sink in the json so it removes a 100 heat / per turn instead of 6 heat / per turn. However on game startup both in normal BattleTech and more importantly RogueTech some process comes along and overwrites the file back to its original spec.

 

 

I have tried editing the files on a 100% clean install with no other mods to eliminate anything to could be overwriting my files via load order and have tried editing mods that should overwrite anything else they get loaded on top of but again any edits I make get overwritten and set back to their original spec.

 

 

Is there some process I am missing that "cleans up" the json files for weapons/equipment? On another note I can edit the json files for mechs mostly successfully as in 500 ton Atlas's with 40 slots in each arm and torso section (Can't edit their speed for some reason still so not 100%) so whatever checks only seems to cover weapons and equipment.
