Not changing version due to clients need to have the same "version" according to forge.

Changes

• added /cave trust and /cave untrust
• added /cave as an alias to /island

How it works

Anyone who is a member of your cave can trust/untrust people. When someone that is trusted on your island does /cave visit to your island, they will be in Survival not spectator. Have a great day!

Note

Make sure to update the islandYlevel to 90 rather than 88 so players don't spawn in the ground and suffocate.
