I wish this had been announced two years ago! I've been running FH on roll20 for the past two years, and the lack of resources has driven me off that platform onto Astral Table. Even though Astral isn't in active development anymore, its easier for me to create character sheets and the like there than on roll20. I got very frustrated with some of roll20's quirks.
That being said, I did create a macro for the Hit Locations table for roll20 that uses the correct distribution on the bell curve. Anyone who wants to know how I did it, assuming you haven't managed on your own, LOL, feel free to let me know. I'm happy to share.
