I actually just got it working. No idea what fixed it, but I unchecked the mods that don't have an effect on world gen and tried to load the game. It loaded so I then left and rechecked them 1 by 1. Now I have them all on again and it loads. No idea why that worked but I'm glad. I really liked this playthrough and would have been upset if I had to start fresh.

Hello all. I have a single player server that I've sunk about 16 hours into with about 15 mods, most being QoL. Today, my friend got the game, so I hosted a multiplayer server after turning off all but about 2 of the mods so I could introduce them to the game. After playing for a couple hours, we got off. I turned my single player mods back on and tried to boot it up, but it's now not loading. It gets stuck cycling from 'It pauses...' through 'It sighs...' every 5 minutes. I'm not sure what to do here since the server has been played with these mods for 16 hours so I don't think I can just turn them off and try to boot up. Does anyone have any recommendations? I'm playing version 1.19.8 and all mods should be up to date. I've been looking through the game files but don't know what I'm looking for and nothing has stood out.

Okay, I think I figured it out. Really unfortunately, its Rivers, which was one of the mods I was most excited about. I'm going to play around with it to see if I can get it to work, but if not, I'll just have to do without.

Interesting. So I decided to follow yalls advice but wanted to try one more time before I deleted the game and redownloaded. I reloaded the mods page with them all deselected and tried a new save; it failed. Interestingly I think whatever was causing the problem was somehow filling the air in caves with stone and changing the natural stone into air because I saw a few stone worm things this time. I then restarted the game for a final try and it loaded fine without any mods, which is weird because I've restarted the game like 5 times before this. I think reloading the mods page followed by the game restart might have been what fixed it. Im going to start slowly adding the mods back and let you guys know if/when it happens again and with what mod.

Thank you for responding @Thorfinn! I went through and deactivated them all (I think. I just unchecked all of them except for the three core codes.) and it won't even generate any landmass still. It should be vanilla since they are all deactivated. I downloaded and originally activated: Better Firepit, Buzzwords, BetterRuins, From Golden Combs, Hanging Oil Lamps, HUD Clock, More Animals, Nails and Strips Clay Mold, Plains and Valleys, Prospect Together, Rivers, Sticks From Firewood. There were a few that I downloaded and then realized they didn't work with 1.19.8, so stayed unchecked: Stone Quarry, Extra Overlays, Auto Map Markers

Hello all. First time posting here. I'm fairly new with 20 or so hours in the game. I've played a couple builder single player games over that time as I've learned the ropes. I finally felt like I had a good enough handle on the game to start fresh with a survival world and some mods. I downloaded about 10 mods and went to create a new world, but i spawned in with no terrain around me. I would then fall into the void and die. I quickly switched to creative in order to fly and see if it was just spawn that hadn't generated, but its the whole world. I then deselected all of the mods and tried again but its still just spawning me in the open air with no chunks to be seen. Has anyone dealt with this before and if so, what caused it and subsequently fixed it?
