When entering the area of Bastet's Pyramid Ruins, the game continuously freezes due to an audio error according to the following error message:
Loading Error
Failed to Load: audio/bgm/El%20Infausto%20Ladr%C3%B3n%20Joyas%20A.ogg
Retry
It will allow you to play for a few seconds after the Retry, but will continuously report the same error every 3+ seconds even if you leave the ruins. Note, that specifically it is the area outside of the ruins, not within the ruins proper. I have not been able to test if this extends to all of the ruins for obvious reasons.
