Hello,
I'm sorry for my english, i'm french.
I have a strange problem in twilight forest. When i put a trophy on pedestal trophy to enter in maze, i have a error "twilightforest.trophy_pedestal.ineligible".
I think is a bug but i'm blocked with that, i can 't have journeymap if i can't enter in maze

^^
Hope you can fix it.

Thank you very much

The only bug here is that the message is missing proper localization and its not showing you a readable message, which i believe was fixed in 3.1.1(at least for english localization, i dont think TF has french localization)

double check the advancements for the TF and that you have all the required boss kills for entering, quite possibly its the Hydra boss kill you are missing.
