Replaced text is not saved

Hello,

When you try to fast change things (like remove a prefix used in every task in the diagram) the save function does NOT work. You see it changed on the screen, but then you save the diagram, close and reopen - all your changes are gone. My educated guess is that there is some kind of optimization on what to repackage what not and the find replace doesn't act like an actual change so it is not saved/updated.

If you do the same change manually it does.

Feel free to contact me for further details/testing.

Thanks:

Tamas
