MultiField: Refresh Paths problem(really big problem)

[Milea Ionut]

I have imported all the German states with cities. In German language you have umlauts and those letters must be in text(paths) translated like this: Munchen(the "u" is with umlaut but I see that the forum do not want to accept it) as a path is /muenchen. The system imported in path those letters like this Munchen as a path is /munchen. After spending more than 2 hours in changing all those letters for all the cities that implied the change, I found out that clicking on refresh button of the "MultiField: Refresh Paths" will revert the paths to the initial state.

This is a huge problem when all the edited links will revert and they will be transformed in 404 error.
