Is there a particular reason why you're removing items/entities/techs in data-final-fixes rather than data-updates?
Primarily because I allow other mod makers to addthings to my mod which I leave availiable to do in data-updates so in order ot get all that data it waits until data-final-fixes to do things.
By all means add things in data-final-fixes. But you should think long and hard about removing things at that stage.
