I really do hate coming to these forums to talk about the huge faults to this program I love so much, but there's really nowhere else I can vent.  My question is, have they fixed the problems with ecosytems yet?  I'm pretty sure I have Vue 7 infinite's most recent update, but I dont see any change to the problems of ecosytems.  I'm so tired of not being able to undo anything because it'll mean my ecosytems with disappear.  And now I'm finding other odd ways that this happens.  I've been working on a picture for a while now, without any problem to the ecosystem, but for some reason now when I render the picture, they disappear.  They're there before I render.  They're there if I select the terrain and look at it.  But the moment I render, they're gone.  I'm so tired of this. 
Again, I'm sorry to come here so angry but this really is driving me nuts.
