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
Sorry, I forgot to add the 'z' thing to the rolls. Also, when I added the extra Perception checks for beating the DC 15, it seemed to move down all the previous ones. I rolled pretty well in general, though, so... yeah.
