This must be a bug.
I recently started an entirely new project. After setting up my initial page and thinking I was going to be leveraging a lot of FontAwesome Pro in this project, I copied the entire latest FA Pro folder structure into my Resources (/resources/fa). I immediately regretted this since FAPro is HUGE and Rapidweaver 8 simply choked and became non-performant trying to manage/save/upload 7K+ resource files (about 60mb) (I had Copy Into set on resource management).
Backing up a step, I just uploaded the FA Pro install directly to my server and deleted the resources from my RW project.
However, the project remains bloated (over 80mb) and non-performant. Saves takes minutes (and RW wants to save every time I publish a test). The project itself is currently trivial (2 or 3 pages with no content to speak of, they are just scaffolding).
I’ve been trying to figure out a way to “compress” the project (I could have sworn there was an option in RW to do this, but, alas, not).
Fortunately, I am not too far along and the project is just for funsies anyway. It’s easy enough for me to just make an entirely new project and start over, a bit warier and wiser now.
