Dorg asked me to post this as possibly indicating that nature shops should not have the donation option.
Description: Nature shops (the ones that sell amulets of the great oak, etc.) have the standard temple donation script, for donation, The first bit of dialogue refers to the "Nature's Temple Donation center" (edit: Criss states "my little green corner in Hempstead," so if custom dialogue was added, maybe it's just a text bug, rather than the donation aspect being unintended for nature shops) but then states "would you like to donate to the temple of ?" and the donation receipt similarly just leaves a space where the name of what you are donating to should go.
Location: Definitely at Criss the Natural Goods Supplier, and Ghaston the Herbalist, both in Hempstead, I haven't checked at any other shops/temples of this kind.

Reproducable: Yes.
