I've only rang my gong twice, all my originals had died so they did'nt get a chance to see it in full glory. So both times i used a lazy villager in case they took him, (he's one of my uglies too) but it said lose tech. My points did'nt seem to go down that i could notice, so i dont know what tech i lost. Should count my self lucky really. Congrats Tibicar in completing all your puzzles too.
