Minecraft Username: 314. Brief Description: Joining the lobby occasionally (~80-90% of the time) results in long-lasting "loading terrain" screens, which then fails and forces me to attempt another reconnection. This does not happen on VMR or the main server, exclusively on the lobby. Instructions: /server lobby from either VMR or the main server. Wait while the "Loading terrain" screen is displayed and never disappears. Be forced back to the server list. Repeat steps 2 and 3 ad absurdum or wait a few hours and hope that it works again. How many times did you recreate this bug?: Far too many times. As I mentioned above, ~80-90% of all /server lobby attempts. Result: "Loading terrain". Expected Result: The ability to join the lobby and properly react to rule violations. Evidence: (I could have probably taken screenshots instead of a 1080p video...)
I fixed it by switching to a vanilla client to leave vmr. The mods I usually have are Macro and Optifine. Having Macros installed seems to be the cause. Even an empty config with no scripts or keybinds gets you kicked.
