None of them are starred because that's saved locally and after I reinstalled it they'd have been reset, and I haven't found any so definitely none favourited. I have all of the filters said to show and bumped the ping up to 500 though there should be many below 100, and still no servers. It seems to be visual though, as when allowing all those filters, the client starts lagging like it always has when loading a lot of servers at once. Then it eventually stops that lagging and says 0 servers found. It just doesn't want to show them.
Thank you for the suggestions by the way.
