uSkyBlock 3.4.2 is a patch release that prevents accidental island loss when accepting party invites.

Invite confirmation

• Accepting an island invite when you already have an island now requires confirmation. Previously, /is accept would silently delete your existing island — a single misclick could cause irreversible data loss. The command now uses the same "repeat to confirm" safety gate as /is leave and /is restart. (#139)
