Hello,  
I’ve uploaded a new extension with fan-made material to the Band of Brother page and for some reason, it does appear as missing. Maybe it’s just a delay in moderation, in which case no problem. I’m asking because I used a colon ‘:’ in the file name and I’m worried that it might be a problem. g.

Colons are not allowed in filenames on any file system that Windows uses (FAT, VFAT, NTFS), or with MacOS HFS(+), so that could definitely be a problem.

Thank you. I changed the name of the file, removing the colon, and everything is ok now.
