I have that problem even worse in that I have to work with a developer who will actively develop like that. Every time he has to add a feature, instead of adding it into the relevant module, he'll add it into 2 or 3 different module which have the knock-on effect of doing what he wants. It took me months to take his spaghetti code, modularise it, and yet still every time he commits is a constant argument of things being in the wrong place in code.
