While testing a map, the shrines and some room props disappeared from the map. Saving and restarting the game did not fix the issue. The rooms were fixed by selling and re-laying that room but there was no way to bring the shrines back. When the shrines disappeared, the frame rate dropped to what seemed like 1 frame ever few seconds. I had to kill WFTO with the task manager. This all happened with the latest version of WFTO 1.6.
