Yep, i am sure they are on it. Practice on honestly any update to fantasy grounds but especially a large update, if you use extensions, do not update honestly for a week and check out the forums to see if there are issues. Unfortunately there’s no way to go in reverse with fantasy grounds. So if even one player updates, essentially you all have to. And then you become the one to let the developers nurse know when you find bugs.

Please remember that the extensions are always a risk and that at least for Pathfinder almost all the extensions are free.
