I have heard that some people gets softlocked in the second encounter. I can't find any bugs, but I completely forgot to mention the temperature system I implemented.
One must use the firestone spells in the magic menu to increase the temperature for grilling after adding the chicken. To defeat the second encounter, do the following; use the "strong firestone" spell > add chicken > add spice, and use the "cook/stir" command a few times.
