Skyblock island border particles missing

The island border effect does not always render after world changes, fast teleportation, or immediate reconnects. The issue is visual, but it can still confuse players when trying to confirm island limits.

• Does not block gameplay or rank benefits
• Mainly affects visual clarity around island borders
• Most noticeable after teleport-heavy sessions

This issue is not critical, but it should be corrected for a more polished Skyblock experience.
