Some things I learned…

• Lithos 32X Texture Pack https://modrinth.com/resourcepack/lithos
• Summon generator https://www.gamergeeks.net/apps/minecraft/mob-generator
• Online NBT editor: https://irath96.github.io/webNBT/
• To make an “X” treasure map, get a filled map, note it's ID, then run /give @s filled_map{map:<ID_goes_here>,Decorations:[{id:“”,type:26,x:<X>,z:<Z>,rot:0.0}]}
• Good level datapacks at https://www.stardustlabs.net/
• To control input signal to a calibrated sculker box, you can use a compost bin with a comparator. Each level of compost corresponds to one level of redstone on the comparator's output.
• https://github.com/Multiverse/Multiverse-Core is good for handling multiple words on a single server
