Whenever I try to join a certain server, it thinks my client is hacked and gives the following message: Hacked: Your client did not send a UUID, this server is not configured to accept such a client. My terraria is not hacked, and I tried redownloading it through steam, and it gives the same error. When I have steam validate the game files, it says: 'One files failed to validate and will be redownloaded' But, if I validate it again it still says the same thing, as if either it's not downloading it or it's downloading a corrupt file. Anyone know what could be causing this or what I should do? Any help would be appreciated!
