Might have discovered a bug?
I've noticed that every time i make a bank i get 2 doubles. E.g now i have two patches called "Darkmess" even though i only have 1 file called that. If i remove the 1 filled called Darkmess, and try again; now i have no patch called that.
Before that i made a bank and i had two patches named "Death", so i removed the file called "Death" from the folder, tried again, same thing, no patch now exists with that name.
So it does not seem like i have named two patches the same thing.
I have used 128 files in the folder, no more, no less.
edit: yeah, if i remove "Darkmess", now i instead have two patches called "Dancechord", so it just took the next file in order and made it a double.
