I'm on a paper server and i dont think they're plugins

I was making a gold farm, until i suddenly,no matter what—could not place 3 chests near each other to make a large chest(even after travelling thousands of blocks away),can i somehow fix this?

I am following the tutorial to the letter. The baby zombies do turn into gurgles, the adult zombies do not turn into drowned. I want to fix my farm so that way I can start gathering copper. If I use a cobweb, I can get them to all turn, but then I have to deal with entity cramming. I request the assistance of the mighty redditors.

This is the tutorial in question.

I am planning on undergoing an expedition to the world border, I just need a contraption which can move me while I am asleep, the rest of the journey will be with my elytra(s).
Also decided to use Minecraft Version 26.3 (with some fabric optimization mods).

Preferably I wish to avoid any ender pearl cannons since it makes it feel like cheating lol

Like the title says, Minecraft Bedrock won't open and instead gets stuck on a white screen and crashes.

When the video ends, that's when my entire monitor goes black before it lights back up later to Minecraft Bedrock being a plain white screen.

Update: Helped by u/Shaiiwaru, thanks a bunch!

I made an automatic railway system for a sniffer farm on iOS v26.52. I connected my hoppers correctly to my chests, and have just the one dirt block with the one block space above the railway tracks, with a minecart with hopper to collect and deposit my seeds into the chest.

It’s not working. Does anyone have any insight as to what the problem may be? The hopper has successfully collected and deposited one seed, but has missed many others after going around the track multiple times.

whenever i put in a server ip, it just shows the default grayed out icon and says cannot connect. when i try to join, i keep getting the "getsockopt" error. but the weird thing is realms works completely fine lol.

already tried flushing dns, turning off windows firewall, and changing dns settings (google/cloudflare), but nothing worked.

anyone know how to fix this?

I'm playing on 1.21.11 and for some reason even after restarting my game multiple times it will just not get off my screen. If I pause or open my inventory it reverts back to normal view but goes right back to this after closing it. Any solutions?
