TS5 doesn’t update the Server Banner if it isn’t already displayed (server info on the right) and loads in a cached (old) image if you display something else in the meantime. Eg clicking on a channel and go back to the server, or display server chat etc.
You have to see the servs banner, wait the servers set banner refresh intervall to see a new image and if you do anything else the new image is gone and it loads an old (maybe the first displayed) banner. I don’t think this is intended
Also suggestion: would be nice if the Server Banner is at least displayed at the server name like channel banners do (ofc with working refresh), so it is a little bit more prominent.
