That's a rather...extreme update. Oh well, I guess it's a good thing I wasn't too far into that terrain.
well a lot of people have this problem, but ofcourse I'm not sure if I deleted that stuff myself (could be
). But when you copy your terrain data to the editor folder you still can paint over it (dunno about terrain editing) but not with the "old" materials, only when you apply a new material to the terrain.
