[Crash] Je ne comprend pas ce qui fait ça

[Phenix246]

Bonjours, je rencontre un problème que je ne comprend vraimant pas :

Voila comment ça c'est passé, je venais de faire mon fichier de configuration, je lance le jeu et une map tout ce passe bien.
Après je vais manger et après en revenant je retente l'opération et lors du chargement de la map le jeu crah.

J'ai essayé de réinstaller les sources de forge mais cela n'a rien changé.

Vérifie les escaliers ajoutés par ton mod, tu as un problème avec les collisions
