If I tested your mod with my particular save and gave me an extra $100,000 just for the heck of it (again, I don't know how your mod works, but you talked about money), I wouldn't be able to say "it is safe" even if I had no troubles whatsoever. Computers and software work in mysterious ways (to me at least). I am playing an MMO where a change to some OP items suddenly made people's key binds disappear. There was neither rhyme nor reason to it yet it happened. There only needs to be one connection - which of course shouldn't be there but is somewhere deep in the code - to mess up things. I have no idea what happened here. But a mod can cause problems - even if the mod in and of itself is sound and even if the game without any mod is sound, just the combination does not work. And from my point of view: if a game works without problems without a mod, and the mod causes problems, it is the mod's fault (again, I don't know if the mod causes problems). Yes, some untoward programming in the main game may be the key component, but as long as the main game works, the mod needs to find its way around this bad lines of code. It's not a question of "how could these innocent lines of code do that" - if they do it for whatever reason it is a problem. And that is a problem of the external program.
