Spontaneous Edifice does not trigger "have [X] buildings" acheievements
I just got my 350th Chancemaker for the first time by casting Spontaneous Edifice. However, I was not awarded with the "Dicey business" achievement for having 350 Chancemakers. Reloading the browser window caused it to be awarded, however.
I'm guessing the Spontaneous Edifice code needs to be updated to check whether any new achievements should be granted due to the new building.
