[1] Your team bank can't be duped anymore. If two people in the same team hit withdraw at the same moment, both withdrawals went through on the same balance, so the team walked away with more money than the bank ever held. It was easiest to pull off from the bank menu, since the amount you type goes through chat and that runs on its own thread, but two people clicking at once was enough. The bank now takes the money out in one step straight on the database, so the same balance can't be spent twice, even by two players on two different servers. Nothing to migrate, just drop it in.

[2] That same fix covers everywhere else money moves through the bank. Deposits, tier upgrades, quest money rewards and anything you pay for out of the bank all use the same safe deduction now, so none of them can lose or double money when they happen at the same time as something else.

[3] People who weren't in your team stopped showing up in it. If you accepted an invite or joined a public team while you were already in another team, the database correctly turned you down, but the member list added you anyway and left a ghost behind. It listens to the database now, so that can't happen.

[4] Members actually show up across the network now. A join, leave or kick on one server didn't always reach the others, so the same team could look different depending on which server you were standing on. Membership is pulled fresh from the database on every server now, on both Redis and MySQL-only setups.

[5] No more duplicate or leftover names in the member list. The list you see and the internal "who's in which team" lookup could quietly fall out of step with each other. They're rebuilt together from one source now, so no doubles and no stragglers.

[6] Turning off an alias like /party works on /team reload now. Before, switching it off in commands.yml did nothing until a full server restart because the command stayed registered the whole time. Now /team reload drops it on the spot, and brings back any you switch on, so the name is free for other plugins right away. If someone still sees it in their tab-complete, they just need to rejoin.

[7] Works on Paper 1.21.x, Purpur, Folia and Spigot, with cross-server over Redis or MySQL.
