Luvin' the game btw:
found a possible bug:
after leaving my first town to quest/lvl/find-stuff, my water node had finished constructing its shrine and i decided to convert it to a death node since i now had 50 mana to spare.
after converting it to a death node, it lost its shrine, ok fine i'll build another - but it wouldn't let me. I have the tech, the build button is there and not greyed out when the node is selected, but pressing it does nothing. So the node is stuck in a shrineless state. Mouseover of the node says i need the tech (which i have).
