During our tests with Beta 5, it has come to our attention that a critical bug was detected during the event in which EXEC_METAFALICA/. is sung: right after the boss battle that takes place as the song is sung, there is a point in which the screen turns white and the music changes. At this point, the game locks up completely, preventing players from advancing further.
Therefore, we have addressed this and released a Beta 5a with the fix for this freeze. If you are playing Beta 5, please come over to the forums and download this update so you don’t run into this problem.
