A plugin has recently surfaced called Terra World Generator, which overhauls the generation of the world! I believe this would be neat to have, as the generation is wonderful. It's free and would be fun to play on a server with! It does have customizability, but for the sake of simplicity it's vanilla settings are cool too. https://www.spigotmc.org/resources/terra.85151/

So I'm trying to make use of the built in GeyserMC stuff to play some mc with some bedrock buddies. To test if it works, I try to join on my iOS device, but whenever I try to type the join command, it crashes the second I enter /. I'm thinking it crashes loading the chat command tooltips and crashes me. Any idea how I can fix this?
