1. Quand on clique sur un items pour le déplacer, il est directement remis à sa place donc impossible de déplacer les items et si on fais clique molette et qu’on met un objet dans un autre slot et puis qu’on clique dessus, il disparait
2. Quand j’arrive à mettre un item dans un de mes slots perso, quand je ferme l’inventaire il est droppé

Je crois qu’il faut utiliser les nbttag et/ou les paquets mais je ne sais pas comment m’y prendre.
