I've hadn't heard of it before and certainly never experienced it. Upon briefly looking into it, it seems to be an issue that sometimes crops up with editing item ratios in the in game frans menu, though its something that happens very infrequently and can be solved by restoring the default setting on the same in game menu.
My advice; don't worry about the issue, and go ahead and install them mod. You probably won't see the issue and if you do it will be easy to fix.
