Poor Quality Potions Always Show Red Solo Cup — Even at High Spellcaster Rank

After a Spellcaster Sim discovers a potion through experimentation, every single one they brew after that shows up as Poor quality, no matter what. This happens even when the Sim is at Spellcaster Rank 3, is in a good mood, and is using fresh, non-spoiled ingredients.

Also, instead of showing the correct potion bottle model, the potions show up as a Red Solo Cup. The only time the potion looks normal (with a real bottle and Normal quality) is the very first time it’s made during discovery. After that, even if I keep making it, it’s always Poor quality and has the red cup.
