Hi Ryan,

: Duplicate hierachy bugged since update today. - #6 by Dormikon
To your question, no, I did not try to undo whatever removed the folders because I did not notice it until the next day. I like to keep a lot of static meshes (thousands) for easier editing, and when I am done I batch them into instanced blueprints. Also I like to work with many nested folder hierarchies to keep things in order. Thus far that was not a problem.
I am wondering if my scene got too heavy with about 16 000 individual actors, but my research showed that you can go up to about 60000 actors. ( notwithstanding the fact that each is a draw call and such a map is not suited for final publishing).
The best way for me to fix this is to separate the static meshes I arranged for the last 2 days by batching them into a blueprint and migrate that back into the last good version of my map.
Here is the zipped log file:

The errors in the outliner are numerous, but they all had been fixed before earlier this year when a similar bug happened in the outliner. Most notably is that “duplicate hierarchy” does not work properly.
