I posted a note to Mr. Lincoln elsewhere, but in case the folks who monitor this topic miss it, I would like to suggest the following to KI:
Put a routine that checks for full backpack and bank (or nearly full) on the sigals to the dungeons, rather than after the person (who overlooked their duty to maintain empty space in their pack) has fought and finally prevailed in battle against the dungeon boss.
So when you *enter* a dungeon, if space needed for likely drops is not available in your pack/bank, Mr. Lincoln says something like "cough cough, young wizard. It seems your backpack and bank are near their capacity and it is possible that you will forfeit some benefit if you don't make some room now, before the battle."
