Bon voila: il y a quelques temps que je joue en LAN avec ma soeur sur minecraft moddé 1.8 avec forge 11.14.4.1577 .
nous avons installé les mods suivants:
-malisiscore-1.8-1.4.
-malisisdoors-1.8-2.5.4
-Mo-Creatures-Mod-1.8
-worldedit-forge-mc1.8-6.1 .
Mais j'ai remarqué qu'avec certains mobs comme les Wyverns et les scorpions, ça me fait quitter le serveur et ca me dit: " A fatal error has occured, this connection is terminated " .
J'ai donc décidé d'ouvrir la page des logs en direct et les logs font soudain apparaitre:
