I'm ending the experiment where my server group played on Bedrock. The parity issues were too annoying. I've commented on it elsewhere. For this run, we will use https://www.reddit.com/r/minecraftseeds/comments/tkatb0/the_island_with_a_village_a_mansion_and_a_huge/ which also gives details on how to find one's own particular wonderful seed to start with.
For this, no plugins EXCEPT for Floodgate and GeyserMC so my nephew can play as well as, hopefully, our grandkids. We shall see how that pans out. No data-packs, no recipes. Honor system, no Fabric mods or other mods. As pure a vanilla experience as we can get. Let the challenge begin!
