Star Fox Adventures Disappearing Fuel Cell Glitch

In SnowHorn Wastes there are two fuel cells accidentally assigned the same flag. Collecting one will make the other disappear.
Not shown in this video, another fuel cell in the same area (near the shrine warp) is assigned the same flag as a buried Bafomdad in the Walled City. Also, two fuel cells are assigned the same flag in Moon Mountain Pass, but one of them is set to never appear anyway.

thanks, you just saved me the trouble of looking through the entire game for the last fuel cell and losing my mind why I can't find it.
