Distant lands mod - Issue with wizard's quest

[JuniTeo]

Hello, so I installed distant lands mod. A few game days after I get a quest from the wizard to get the fruit from the witch swamp and to bring 10 deluxe fertilizers. I go to the witch swamp and complete the cutscene where my character gets the fruit, then my quest is updated to bring 10 deluxe fertilizers to the wizard tower. Since then I enter every day with 10 deluxe fertilizers into the wizard tower and nothing happens. Anyone had this issue before? I am not sure if it's a bug or I'm not doing something right.

If it's relevant: I am playing this mod on an old save (I think I'm in year 8) and also have stardew valley expanded and adventurer's guild expanded mods

Just replying if anyone else bumps into this because it got me puzzled not knowing that it requires a bit of end game, but it's not just any purple Deluxe fertilizer that you can make normally - it's the red one you get from Ginger Island with Qi
