I arrived to the shop in HMV. I did the usual thing I do when entering a newly generated shop: collected all unpaid items and dropped them in a single spot. Except the game crashed when I tried to set up the correct items to be dropped.

Button press sequence was something like:
d (for drop)
9 (for select/deselect items)
5 (for special filters)
5 (for unpaid items)

I think it was at that point ADOM crashed. I could have also managed to press 1 to select all items before crashing, not sure.
