When you unlock the waterfall grotto's entrance (with help from the sewing fan), you can enter the grotto at the waterfall or the camp.
However, when entering through the waterfall entrance, there is no exit area (gameplay wise).
This means, you can screw yourself up, theoretically, when you enter with a weak party that cannot make it to the campfire or other exit.
Also, it just seems like a bug and probably is.
