So there is the Slavic update which was announced and I'm worried about being able to continue working on my mod project in the Kit and on PFM.

Is there a way to keep it from being totally ruined?

The last time this happened the kit updated and completely ruined the mod I was working on.

The tables erased and replaced most of my changes and of course the mod itself wouldn't work because of the update.

I've already made a backup of Kit but I'm not sure how much good that will go when any mods made with it will crash with the new updated Attila.
