3D Editor issue (corrupted waypoints)

[max1944 16]

The old 2D editor works fine but the new 3D editor will corrupt waypoints. Example: In the first campaign mission A_in.Stratis after the helicopter ride Adams (instead of waiting by the truck) will walk to the Kamino firing range (by foot). This makes further progress impossible.

 

It seems the new 3D editor isn't fully compatible with old missions.

Now, 8 months later I tried it again and the 3D editor still screwed up the campaign missions. And with the old 2D editor removed there is no option anymore, which left me basically stranded ...

 

I put a decent amount of time into modding and now I can't do any progress   :(
