my kuo-toa sticky bags (Ktsb) were converted into tanglefoot bags when left in a container with another tanglefoot bags (tb).

i.e.

START: 5 Ktsb + 1 tb;

RELOG: 6 tbs.

It isnt dramatic, as they are the same thing- but I wonder if this happens for other items where it could be more dramatic.

Same happened with me, Choosen Incendiary Pouch became alchimist fire when I picked it up (it stacked up on my existing alchemist fires)

These stackable items need to be given distinct tags.

Fixed.
