Posting to help. For Devs, I am having a similar issue. Coming back to game, I started a fresh account with the holiday special yearly pass. I log in without interface on until I click on that option and I don't receive any offline messages although my character selection menu has the always flashing the red envelope. Rejoined game via download using http://3dxchat.com/support/info. Did a computer flush, reinstalled (although same website) and even tested my internet speed and nothing has helped improve, I didn't experience these issues on same machine back in 2016 before world editor.
