Bug Fixes

• [Exploit] Players can sometimes obtain dupe items by throwing them through nether portals.
• [Exploit] Added a confirm/reject to player coop invites. Malicious players were insta-cooping players and killing them.
• [Exploit] Armor stands could be pulled off islands by visitors using rods.
• [Critical] Server crashes (watchdog timeout) when trying to obtain skulls for TopTen or Warps. Occurs when Mojang server is offline or rate limiting. Heads are now cached and obtained async. Big thanks to PaperSpigot Devs for all your help!!!!!
• [Major] Scanning for a safe spot to teleport could take too long and crash the server with large islands.
• [Major] Performing the level calc could take too long and crash the server with large islands.
• [Major] Coops could make warps on a coop island.
• [Medium] If a player bought items from the minishop but had a full inventory, the item was lost. Now they will be dropped on the ground.
• [Minor] Update to Vietnamese translations.
• [Minor] Auto-detection of player's client language was not working.
• [Minor] Added support for PLANKS in schematics
• [Minor] Door protection was accidentally protecting wooden doors from breakage as well as use.
• [Minor] Warp level restriction was still being used even if 0 or <0 and preventing placing of warp signs.
• [Minor] Biome setting is done async over time. Provided feedback to player on progress and in console. Removed efforts to remove water from dry biomes. Slowed down biome setting to ensure all blocks are set over time.
