Prestige Awards in PFGtOP is completely broken. Particularly the “Fame” ability. Try adding “Fame” 5 times, then add “Free Purchase up to 150 gp”. Okay so far. Now remove one “Fame”. “Fame” is shown in the ability list twice, once as x5 and once as x4. Now select the x4 entry and remove one. Another “Fame” entry appears showing x3. So a total of 3 “Fame” entries are shown. Continue removing “Fame” entries and new “Free Purchase up to 150 gp” entries start appearing.
An unqualified aspect on the ability object was causing the issue here. The code can now cope with that.
