I've made some pretty substantial changes to the alpha sheets behind the scenes, and to the Pathfinder [Legacy] sheet in particular. Please try clearing your browser cache, or post in the Experimental Features forum if there are any issues!
At this point, we highly recommend that all new Pathfinder sheets be created in the alpha and that existing Pathfinder sheets be copied into it via the 'Copy to Sheets Alpha' link in your regular sheet list
I'm caught up(and have been caught up) in the thick of summer renovations with my family, so posting will continue to be sporadic; 3 posts/week looks, unfortunately, to be what the immediate future brings. Sorry.
