Please see here this nasty bug. I lost a lot of hours of work trying to find the solution. I even downloaded Flux.AI, but this project is complex enough that I decided I didn't want to recreate it from scratch. If EasyEDA doesn't fix these bugs, they risk users' frustration turn into migration to another software platform and I'm sure you don't want that.
