v6 - Files do not redownload themselves upon deletion

[boolean]

*with the exception of images, I've noticed that ganis specifically do not redownload themselves on v6 once they've been deleted from one's levels folder. In order for the files to redownload themselves, I had to use v5. Otherwise they simply would not draw.

deleting filenamecache.txt and restarting the game should work aswell. if you have a lot of files in the graal folder it could take a while though until the game finally starts
