I can make out what its supposed to look like a little better but its still messed up.I downloaded both the zip file and the installer both of them look like this.
So it doesn't seem to be related to the texture page size; changing the size shuffles the sprites a little, but the issue is obviously still there. What surprises me is that a couple sprites are correctly displayed... Maybe one of the texture groups is a bit too crowded.
I tried to make a couple more changes, and somehow managed to break the entire project... Is there a way to contact you on the weight gaming forums or reddit once I have figured out this mess? I don't use many social medias, so these are pretty much the only two options I have. It might take me a bit of time, but I want to try a few more things before giving up.
