I'm experiencing an issue where Zotero fails to load the list of libraries/collections in the save interface, and the "Loading Collections" spinner keeps going indefinitely. I have a large personal library so it may be a timeout issue. The save itself works, however the snapshot doesn't end up in the desired location. Maybe loading the most recently used library would be an appropriate fallback or default? (I was able to select a collection previously, and not sure what changed.)
