There are posts from 2014 about this issue. Level blueprints are difficult and frustrating to work with across studios when you can’t see any diffs from other developers, and nearly impossible when you have multiple branches because, of course, changes cannot be merged. They also make duplicating/forking a umap a pain, though that’s a separate issue. Your blueprint diff tools are a godsend, and the fact that they don’t work for level logic is incredibly disappointing and, frankly, infuriating.
An ascii representation would help so much. Any update Epic?
