I've had this happen 3 times now, but not always. I click Pathfinding and after finding one, but before finishing going through the deck, it locks up and simply sits there with the Pathfinding card in the middle of the screen. The only way to get out of it is to refresh the browser.
That's very strange. If it happens again it might be helpful for the devs to see a copy of the log. Instructions are in the How to Report Bugs thread, but I'll repost them here for convenience:
. . . Though that post needs to update the instructions a little: if you type the command "clip" (with no quotation marks) into the console and hit enter, your computer will copy everything in the whole log. Then you can use an ordinary word processor to paste the log, scroll more efficiently to the bottom, and check out anything of interest.
