I don't want to lose my character or any of my other dimensions. I should've included that if it wasn't already apparent enough. Copying over saves and other things from the save folder doesn't work for some odd reason so I can't just transfer over player or dimension data, I already tried early in my playthrough when I didn't like my current world.

Anyways, I got some issues with my world now after installing some new mods and attempting to figure out how to just plainly delete my overworld to get a fresh slate rather than having to travel thousands of blocks, or attempting to find a spot in creative in a decent area far off. I tried playing with things myself without knowing much and i sorta messed things up.. The world still works but it's pretty messed up and I really need to clear the whole thing and it seems to go along with the issue I was having with that inventory problem, deleting/editing files and it not saving over after reopening the world. And with this I'm just plainly deleting the overworld and it's just reappearing as it was and I can't figure out how to generate a new one.. (I am not asking for help in the paragraph below, I am just giving information with what I deal with so give more backstory to reasons what I wanted above) Issues with loading and other problems cause me to die repeatedly (Fall damage when all blocks end up as ghost blocks forcing me to move dimensions or saving and exiting which causes max fall damage when loading back in, falling through the world if chunks don't load and forced to relog and I end up spawning in in the void) while traveling between dimensions so I have keepinventory on, so I very often end up at the spawn chunks and other problems with some mods when entering different dimensions it resets my spawnpoint so I can't really get away from the original spawn chunks easily..

EDIT: I fixed this problem with finding the ID of the item causing the crash, starting up the world in a server and get my player to join, and before my player fully loads I clear that broken item from my inventory that's causing the rendering crashes, and my player loaded in fine since the item was gone. I was having a little trouble getting the server to work since certain client-sided mods cause servers to crash if they try to load it. So I know which item and where it's located in the player's inventory that's repeatedly causing the crash but every time I delete it enitrely, or change it to stone and start the world back up, it'd crash and revert back to the item that's causing the crashes. After saving my changes in the NBTExplorer, I close the explorer and reopen it and reopen the inventory file, and it's still changed, but when I open the world it reverts back? How can I get rid of this item for good? Is this "internal server" messing with it? is my player data saved somewhere else and changing the player data back to when I had the broken item in my inventory when I load up the world? EDIT: This is ran in singleplayer and I am the only player, but I don't believe this changes much about what happens along with any inventory management or entities.

Oh, well that's embarrassing, I found out why real quick

I don't know what caused this to happen, and I haven't done anything since I've had it working. The log is short, there is no crash log, there is no reference to specific mods. The log isn't all that long.
