Greetings Mallaidh,
Once again, thank you for your suggestion! We're always looking for suggestions and feedback that can help us make Potterworld a better place, and we appreciate you bringing your idea forward!
I’ve brought up your idea up with the team and unfortunately, we are declining this suggestion at this time - this is not something that we will be changing back. This is mainly due to the fact that most of ingredients have already been removed and we are unable to restore any of the lost ingredients. The old ingredients were removed because they no longer have a use in Revelius, and we added a whole new set of ingredients to the server (making the old ones useless). Additionally, we do not feel that the old ingredients would be considered "collectibles" and could get confused with the new ones. Again, thank you so much for taking the time to submit this suggestion and we hope that you submit more ideas in the future!
Best regards,
Garrison
