I noticed this morning that 3 procedurally-generated vines changed configuration on their own.
Now I’m generating vines and saving the file and when I reopen the file the vine is completely missing.
The problem still persists?
Vine may generate randomly each time when you open the file. 
Hi,
I just took the PRO version =)
Same problem here, the vines reconfigures itself, and in a very bad way, it becomes a lot smaller, like almost no vine at all. I occurs every time i re-sync the model. I’m on Archicad 27.
I managed to get mine stabilized on one particular model I’ve been working with. Haven’t tried it on a new or different model. The only change I made was to do another clean install of D5 2.6 in an attempt to stop crash to desktop. I did get one CTD yesterday but that seems to be normal.
experiencing the same issue.
