NoAltsExploits v6.4

• 
  Fixed false alt-account history entries on failed joins.
  IP history is now only recorded after a player successfully connects to their initial backend server, instead of during the earlier login phase.
• Improved max-accounts detection accuracy.
  Recent successful connections are now used for account checks, helping reduce false positives from older or stale IP history.
• Fixed same-house alt group handling.
  Configured same-house alt accounts are now checked only against their own group instead of mixing with alt accounts from other configured households.
• Fixed max IP online edge cases.
  The plugin now handles unset or disabled max IP online values more safely.
• General stability and login-flow improvements.
  Adjusted connection tracking logic to better match real network joins and reduce incorrect alt-account blocks.

• Stopped doing file saves while players join/leave, so it won’t slow down the main server loop.
• Made saving happen in the background and “batch up” lots of changes into one save.
• Made saves safer so files don’t get half-written or corrupted if the server stops suddenly.
• Made sure what gets saved is a stable snapshot, not changing mid-save.
• Removed the old extra save system so there’s only one clean way of saving.
• Made sure the plugin still saves one last time properly when the server shuts down.
