Poisons sold in shops stop working
All player-made poisons tested so far stop working when placed into or bought from a shop.
They can be still applied to weapons and show weapon FX, but they do not trigger poison rolls in the combat log.
This is apparently known for a while but I don't think anyone posted it here.
Tested with freshly made poisons before and after placed in a shop. The poisons that were in the shop do not stack with the fresh poisons.
thanks for fixing this
