Cobblemon Realms Core v6.2.6

Fixes

• Fixed Brock's arena and other arenas becoming inaccessible when blocks change state after generation, including boiling cauldrons, fence connections, rails, and healing-machine charge.
• Arena generation now completes with diagnostic warnings if individual blocks cannot be placed. Missing blocks and structural differences no longer lock players out; admin repair and rebuild commands remain available.
• Reapplied schematic block states after placement to preserve authored rotations, rail shapes, connections, and levels. Unsupported properties retain the available block and its supported properties; missing blocks fall back to air.
• Added automatic recovery when entering arenas left failed by earlier recovery policies, including exhausted recovery attempts. Existing schematic files are unchanged.
• Fixed prepared arena slots being reused after their unsaved chunks disappeared, such as after a server restart; absent structures regenerate automatically.
• Replaced normal arena preparation chat messages with a short action-bar status. Arrival is shown only after teleporting; actual failures remain visible in chat.
• Avoided delayed automatic arena teleports while a player is already in an arena, spectating, or in battle.
