Hey there! We appreciate the feedback, however please refrain from posting feedback / bugs in the Reviews and use the discussion thread instead as that is the way Spigot likes things.
1. Lost Inventory - This is usually because of 3rd party inventory management plugins are conflicting with BA. Please open a support ticket so we can fix this conflict.
2. Same as above, please open a ticket. This seems to be custom to your setup and we would need more details to investigate.
However, you can try proactivity fixing this by adding `teleportYOffset: 0.0` to your BA config.yml.
3. All statistics are run / managed through our BattleTracker plugin that handles all death / life / arena events. Please see here:

Please open / create a GitHub issue here:

Thank you!
