Alchemy is the new feature and it´s cool. It should have it´s own buglist.
First the TORCH bug.
Equip a torch and then start alchemy.
Now look around, you have many flames in the sight field.
But now the cool thing! Start to make a new potion. Put water in the pot. The torch stucks in the pot.
You can finish the potion and leave the alchemy. The torch stays in place.
When you leave the hut, you have the handanimation for holding the torch (without torch), but without light.
Look in the inventory, there is the torch, it´s not lost.
You only need to equip the torch new, and everything is okay.
