I'm still having the previous issue.
Also, I have tried just using the "get what you can" setting and I'm having a separate issue where I have to take 1 more than the specified amount for the items full switch to be set to on.
If I set it to 2 maximum items and I pick up 2 items from a chest, the full switch won't be turned on, but if I get 3 items with the "get what you can" command only then will the flag will be turned on.
