Goblin Torturer not dropping Momento Box?

[Jalico]

I have spent one full night (about 5 hours) sitting in the torture chamber (as the camp seems to be as well)

1. attempting to get the goblin torturer to spawn (seemed to be every 5 spawns or so, sometimes more)

2. trying to get the box.

I don't expect to see one everytime I kill him but for a "common" drop according to the wiki (which I understand could be wrong), it does seem to be a bit much for what it is.

I'm curious if the box is dropping at all? if it is dropping, should it be listed more rare than "common"? I have seen 3 eyepatches and no boxes which leads me to believe it is either broken or it is misrepresented in the wiki and needs to be updated.
