@thecabbagedetective Loading files in 2.8 can be a bit of a hassle sometimes, as far as I’ve seen in the streams of Pablo Vasquez (Blender Today), but I suppose it will be better over time.
I myself have only loaded a couple of files, and at least one of them made blender crash.
It’s advised to keep a backup of your 2.79 files before working on them in 2.8, because it’s impossible to load the file back in 2.79 ones you edit them in 2.8. I managed to get a file from 2.8 to 2.79 by exporting to an Alembic file, and then importing that in 2.79. It wasn’t a very clean import though.
