WorldEdit VS Purpur

WorldEdit + WETS.

Import that into Minecraft with the WorldEdit plugin.

It sure is: Git Link

Just by looking at the source code you'll see that they package both the forge and fabric code together.

Check their issues list and see if yours is there. If not, post it. https://github.com/enginehub/worldedit/issues

https://github.com/enginehub/WorldEdit is far more complicated than a Resource Pack. You need additional software to use it.

Yes it is. WorldEdit has been trusted by millions, and if u want to double check the source code, it is available on GitHub. There's also FastAsyncWorldEdit (FAWE), which is a fork of WorldEdit (it's a plugin not a mod) that aims to be faster than WorldEdit.

This could be caused by a lot of things, such as other plugins, etc. If possible, test this on a Paper 1.17.1 server, software, with world edit installed. Then try and do the exact same thing on that test server. Report this on WorldEdit's GitHub Issue Tracker if u think this is an bug

We will be downloading the Minecraft server files into this directory. To preface, there are numerous variations of server JARs that can be used (e.g. Spigot, Paper, Purpur each touting their own benefits). For this tutorial, we will be working with Paper, a fork of Spigot that is optimized for performance.

I Mostly Like Linux as a OS For a Server and PurpurMC (https://purpurmc.org) As a Server Software and i Mostly Use EssentialsX and WorldEdit and More Server Management Stuff.

If you prefer to go the old-school Bukkit/Spigot/Paper/Purpur route (which provides the greatest level of compatibility with pre-existing server plugins), I recommend the latter of the four. Each of these projects is a fork, built on each other in that same order. Each fork offers additional customisation, API, and performance enhancements over its predecessor.

I’d recommend Paper (which is a fork of spigot) or Purpur which is a fork of paper and pufferfish

If you're looking to re-add gravity duping I would recommend not using a plugin but switching your server software to PurpurMC. It is a fork/version of PaperMC that re-adds gravity duping as a config option as well as the ability to toggle back on things like tnt duping and several other features that the PaperMC devs arbitrarily decided were bugs (even though Mojang has explicitly not removed them).

Small addendum:\ If you want to keep using a paper derivative (as a drop-in replacement), you can use purpurMC instead. It provides a config option to enable gravity block duping by disabling sand.fix-duping. (At least for sand)

You can host a small purpur server

Have you tried re-downloading the latest purpur jar file from the purpur website?

tweak some configuration, try lower your entities spawn, I at last you might want to try PurPurMC for the server, it's paper fork with some modification, I feel a lot of improvement since using this fork...
