Problème en ouvrant un monde solo et en me connectant à un serveur

[la rédac' du renard]

Tout est dans le titre. Je me fait un serv moddé avec quelques amis et pour le moment je le test, mais j'arrive même pas à lancer une game quelle qu'elle soit. J'ai un log bien-sûr, que je vais copier-coller en dessous, mais vu que je sais pas lire ce genre de trucs (ou tout du moins pas suffisamment en profondeur pour résoudre mon problème) je m'en remet à des gens plus compétents que moi.
Du coup le log:
