I recommend you update the plugin immediately as the following bug fixes are critical.
- Fixed where Effects are not removed when the beacon is broken
- Fixed where Effects are not removed properly
- Fixed where Effects are not removed when the beacon is unloaded
- Fixed where GUI is still open even the beacon is broken/unloaded
- Added Beacon Particle Condition (reset your beacon.yml to use this option)
- [API] Removed "handleJoin(LivingEntity, BeaconData)"
