A few quick notes from my 1.14 related activities:
I fished for bamboo (long story about that later)
Here is the longer story behind my quest for bamboo and sweet berry bushes.
* I wanted to get Bamboo, so I looked for an easily accesible Jungle to fish in and settled on one north of Mordor. This seemed better than exploring the map in search of a new Jungle with bamboo growing. I fished for a long time before I realized that a Fishing Rod with Luck of the Sea would never get bamboo. Fortunatly, one of the things I did get was a fishing rod with Mending and Lure III which I started using. It still took a while to get bamboo, but in the meantime...
* My fishing spot was on a shoal in 1-deep water a ways off the coast. A gurgling noise alerted me to a Drowned approaching from the nearby deep. I easily dispatched it and went back to fishing, but started periodically looking around for other mobs. On one occasion I turned to look behind me and my heart skipped a beat - I was literally face to face with several strange entities!! Calm returned once I identified them as a Wandering Trader with 2 llamas in tow and I went back to fishing. As night fell the Trader drank an Invisibility potion, leaving the leads from the llamas dangling in the air toward the potion effect particles throughout the night. After dawn the Trader wandered to shore and into the Jungle a short distance. I pondered whether I could get the llamas through Mordor to the Green. A quick check on the wiki confirmed the llamas could be separated from the Trader, so I went ashore. Attempts to use the fishing pole to pull the trader far enough away from the llamas to beak the leads wern't getting the job done in the close quarters of the jungle, so I killed the Trader instead. Suddenly I was under attack - the llamas were spitting at me! Not wanting to kill, or be killed by, them I ran back toward my fishing spot with the llamas in hot pursuit. They stopped following me at the waters edge. After a short while I started back toward them and they did not attack me anymore. I went to where I killed the Trader, picked up the 2 leads that were dropped, leashed up the llamas, led them out to my fishing spot, and tethered them to a fence post so they wouln't wander away. At this point I realized there would be no need to lead them through Mordor - I could simply get new ones when a Trader appeared on the Green itself. Duh. The llamas are still tethered there, next to a bed and an enderchest. Someday as a personal challenge I will go back for them and lead them safely through Mordor to the Green!
* My search for Sweet Berry Bushes would have to involve new chunks. I used the online map to locate an existing Taiga biome that had unexplored territory adjacent to it that I could reasonably get to. My starting point was the Prismarine Grinder and method of travel was Elytra. It was an adventure to fly safely while checking the online map against my in hand map and scanning the ground below (and in front) to navigate to where I intended to go. I knew I was in new chunks when I spotted a new format Desert village on the edge of Taiga with the terrain merged smoothly. I landed to check out the village and search the Taiga. Strangely, the villagers trade interfaces would not stay open. Night was falling and I didn't want to endanger the villagers with the mobs that would be spawning, so had to break the bed out from under a sleeping child villager to kick it out so I could use it for myself. That's the first time in many years that I've intentionally skipped the night. Now with it day again I went into the Taiga and almost immediately found Sweet Berry Bushes. I gathered up a handful and left many. The flight back to the Prismarine Grinder was another adventure in navigation due to slow loading chunks that contained looming mountains.
* Concerned about the villager trading interfaces not staying open I went to my large villager trading hall. Since in the past I had only traded with a small number of the villagers there I found I now have a large hall mostly full of nitwits. Sigh. I'll be working on revamping it all into a new villager breeding and trading hall complex with an iron grinder.
