I recommend using an aftermarket launcher that handles forge, fabric, etc. This will make handling worlds, screenshots, mods, java, forge, fabric, or whatever else you need all in one place. With a launcher like MultiMC, you only need to click on the forge version you need, and the launcher will handle the rest.
The only caveat is that you will need to install Java manually in most cases due to EULA issues, but it is pretty much a one-and-done thing.
That is a really, really weird way to use the fill command, but yes, it should work; you might have to specify that the cords are in the Nether in the syntax if you are doing it by cords.
I would start by taking out every mod one at a time and see which one is the troublemaker. If it is just flans (which I think it is idk) then see if it has a texture pack that might need to be enabled
there should be a way to summon the nitwit specifically which is a rare variant of a villager that has a low chance of spawning that will refuse to take up a job. Use that and it will look like a villager with no job
As long as your hacks don't break the terms and service, no... you cannot get banned, but if you are trying to force op and steel account credentials, there would be a good case to ban you account.
But if you just wanna fly and dupe stuff, your chillin.
If you want a clean picture of a large item, turn up you fov, add a shader, and preferably a nice texturepack. If you are rocking Nvidia, you can run seus ptgi and get very nice pictures. Turn up all your settings to max, because frame rate doesn't matter when you are taking a screenshot. Get an angle that shows off as much of the ship as possible. Then just press f11 and then f2 to get your screenshot.
This is often due to settings set by the admin of the server that limits server wide mob caps. Does your farm work better when no ones online? If so that is the case, if not, ask your admin if there are any plugins on the server that effects mob spawning.
So if this were me, I would copy over the player data, dim1, dim2, and dim3 (over world, nether, and end) folder over to a fresh world save and it should let you continue off exactly where you left off. Just change the world to hardcore also. Good luck, lmk if you get lost along the way.
.schem is for world edit/fawe not schematica or litematica. I would paste it via world edit on a local world, and then make it a saved schematic via either litematica or schematica.
I use a client side mod called tweekaroo where you can adjust acceleration and deceleration values. Some servers detect the mod as a hack, so be warned.
Does mine craft itself crash or just when you open up a world, or is it when you load the texture pack. Because each of those have a different fix. Most likely it is an optifine or ram thing if I had to guess.
