Hello Buff,
Not sure how steam updates work but I don't think it will Corrupt any savefiles in the upcomming build. That said, there may be a time when it'll happen as we're expanding the map ( for the goblin arc), doing skill rework and some overall changes on the QoL aspect ( i reckon you'll see some glimpse of it in the next build :) ). As for TF aspect, I don't think so.
Hope this helps. :)
