Yes, there are actually a couple of things you can do, if you don't mind starting over. The first is to uninstall the game (leaving the savegame files intact - you might want to back them up first, just in case), then re-download and install the free trial (assuming that you're playing the Windows version). Next, launch VV5 and pause the game that you're playing in the first player slot (to preserve it in case you want to continue it after the fix is available). Once the game is paused, go to the Menu, click Change Player, and start a new game in another player slot. The new game should have the heathen mommy puzzle working properly.

If, for some reason, that doesn't resolve the situation, or if you don't want to preserve your existing game, you can completely uninstall the game, delete everything in your savegame folder (located in \My Documents\LDW\Virtual Villagers - New Believers), re-download the game and start completely fresh.

Let us know if you have any trouble with this workaround.
