So there's a minehut server that i have made to play vanilla with my friends, and we were waiting for turtle eggs to hatch, and to speed it up, i made the tick speed to around 50000, which i have found out will crash the minehut, i was sent to a world to verify that i was not a robot, and then i always get timed out, or the io.netty... etc etc, and now i cant get in, and when i do, chunks of the world are missing, and its possible to fall through, and then i proceed to get thrown out again. I tried sending a command to the server from the website, to set the tic speed to 3, which is the default, but that is not working either, what can i do to fix it?
