# ** Battle Report v 1.6 by Illustrationism
# * Posted & Edited by Raziel
#==============================================================================
# A script that shows the battle result like in the Final Fantasy games.
#
# Features
# * Scrolling down Exp
#
# Edits:
# * Exp Bars filling up
# * Possible displaying of Facesets instead of Charactersets
# * Exp scrolling down faster, depending on how much exp you gain after battle.
# * Play a ME as long as you want in the result window.

En gros, le problème c'est que ton script s’exécute après un autre, qui à déjà fermé la fenêtre concerné.
( En regardant très très vite fait, je vois pas trop d'où ça viens, mais j'avoue m'y être penché que d'un quart d’œil )

J'ai un peu la flemme de vraiment regarder ( surtout que l'indentation avec les spoilers est ignoble, recopie / colle avec les balise code, histoire qu'elle soit correcte ), mais déjà, de ce que je vois, la fonction draw_actor_hp est réécrite dans les deux autres scripts que tu donnes, et j'avoue qu ça me parait bizarre.
Les deux autres script sont vraiment nécessaire ?

Envoie une démo de ton projet avec l'erreur, je verrais plus tard pour essayer de comprendre l'erreur.

Edit : Ah, bah, t'as déjà mis la démo, je vais m'y pencher de suite au final xD

Edit 2 :
Après avoir regarder un peu plus en détail, je comprend même pas comment ce script peut marcher Oo.

En gros le problème, c'est que le script Battle Report v 1.6 dispose ( efface si tu préfères ) les fenêtres de base, comme la fenêtre de statut, de message, d'aide ... Alors que toutes ces fenêtres sont de nouveau dispose dans le script Scene_Battle1 lors du changement de scène.
Chose qui fait tout bugguer puisque la fenêtre à déjà été dispose, et ne peut donc pas être à nouveau dispose.

Remplace ton script Battle Report v 1.6 par :

Ça réglera le problème.

Par contre, je comprend même pas comment ce script aurait pu marcher, la seule option que je vois c'est qu'il manque un autre script qui changerait la fonction main du Scene_Battle en profondeur, mais en jetant vite fait un œil, c'est pas le cas.
Donc j'ai vraiment l'impression que ce script à été fait soit à l'arrache sans avoir été testé, soit dans un but plus précis, et qu'il te manque un script.
( Mais ma correction devrait marcher, même si c'est pas forcement parfait ).
