This version is 99% production-ready but i marked it as beta while waiting for more tests and reported issues.
Teams can now have one or more shared enderchest (with variable size)
permission to use the echest: ultimateteams.team.echest
Team Echests are not compatible with cross-server yet
Admins can view, manage, delete, add, backup and rollback teams echests with their dedicated command **/teamadmin echest **
other fixes/additions:
delete both your config.yml and messages.yml files
enable enderchest migration in the config, wait for the server to start, then disable it and restart again.
Thanks to dei0 for the echest system. check out his fork of ultimateteams, that features a slighly different team management (like upgrades for more members and warps)
in the next version i will convert the messages file to a new format, and it will be published probably within 2-3 days, so i wouldn't recommend you to change the messages file after it regenerates, since you will have to do it again.
i am also gonna add a little bank system, featuring only team balance for now, but with the future vision of adding an optional level system.

A simple yet complete Teams/Clans plugin for Minecraft, with cross-server support.
