Something I realized while following up a newsgroup post. If you knew an item's bless/curse state and dipped it into water while blind, the bknown flag stayed set and you learned the item's new bless/curse state without seeing any "glows blue/black/&c" feedback. Clear the flag unless you know that the potion being dipped into is water (or is clear if not water has not been discovered) and also know the water potion's own bless/curse state.
