I think it may have been a 'lag issue', but I'm not sure.
I was brewing potions and all was going well. But, one potion did not show in my inventory. The log shows the bottles, gold and XP gone, the casting as a success, and that I got the potions. But, I searched and there were none in my inventory. Now I thought maybe it was a stacking problem, but the only I had were those that I was already in possession of before brewing.
I'm hoping this is not a common bug and it was just an odd occurence.
Guess it was a one time fluke. Has not happened sense.
Please disregard.
