I was looking at the bank problem, got two images, one second one I closed the spaces up in the banking in scripts. Which I think was one problem the other seems to be or may be a renamed sound file.
I for my self did finish all the untranslated stuff, which was not very much, a very good translation over all on this one.
I am wondering Did banking work before the script translation?
Don't have the original Japanese .rgss2a to check change's or what may have accidentally been removed by the translation, maybe someone else can check differences. It may be something similar to the trouble you get when changing the name of .png images.
