Nintendo has recently released a report saying that the Tecmo and Grasshopper Manufacture developed Fatal Frame IV: Mask of the Lunar Eclipse has three bugs, one of which will cause the game to crash. However, none of these bugs will affect save data.

The game-crashing bug can be described as follows:

quote duckroll, GAF

During "三 ノ 蝕 忘 日" (it's a day/chapter in the game I believe) after you have obtained the 暗 号 の よ う な メ モ (coded memo), if you open the door to the doctor's room on the 2nd floor of the hospital the game will lock up. To avoid this, after getting the memo go to the director's office in the first floor and enter the 3 digit code into the interphone first.

The other two bugs concern empty data, with the spirit profiles for No.s 32, 101, 174, 176, 182, 211, resulting in a total of 227 spirits instead of the original 233. The last bug is that one of the Extras section that is unlocked after the game is cleared is unselectable.
