Those black spots on the map once rendered will be fixed now (Hopefully). I got a message from the Dynmap developer where he fixed CTM handling issues that caused using custom texture packs to fail loading with shulker boxes and then the second issue of the black spots when using an older pack.

I won’t be doing a full render as it takes a very long time and destroys the TPS, but you can help fix the map by just playing! it’ll auto re-render the areas once you visit them now, I turned on movement triggering a render again until all the black spots are fixed. You can also trigger an area to render by, placing or breaking a block, burn a block, move a piston grow something etc.

• Updated the Live map and hopefully fixed the rendering issues (Black spots) you will need to visit your areas to re-render them.
• Updated the main server Spigot server
• Updated main Bungee Proxy server
• Updated main OS
• Updated Chat plugin
• Updated a supplementary plugin that works with anti-cheat.
