This seems to be a pretty known topic for this mudpack, an with so many mods I expect it to be somewhat unstable and risky. I went two weeks into a world, but got to a point it started to crash. The only backup that worked was the previous day so I lost a days worth of work. I got back the pretty much the same point, then the world crashed again but the backup a few hours before worked.
A few things to note I don't have a crash log, but here are the things in common that happed. Both times it crashed and broke the world I was using the charm of dislocation in the mining world, to the sky lands world. I also had a large amount of auto crafting benches making quad cobblestone. In face the second time it crashed I had a whole stack of benches making compressed cobble, went to the mining world with the charm, forgot food and use it again to go back to the base, then it crashed.
I started a new world today and went with garden of glass. Tbh I think it was something with mods clashing though. The end of the crash log mentioned EnderIO was conflicting with AE2. The pack wouldn't work with either mod being deleted. Unfortunately after realizing I couldn't trust my world anymore due to crashing I gave up for a bit.
usually crash logs from enderio say that it might be conflicting with AE2, but in most cases everything is fine. can you post the crashlogs you have, please? and make absolutely sure there are none for the first crash. unless your pc shuts down, there is always a forge log in .minecraft/logs
Thanks for the reply. I deleted Project Ozone 2 from my game list the night it happened out of anger. I did copy the world folder though. I downloaded a new Po2 and added the world to my saves and got the crash at the same point. It tries to load, then the second its about to be playable it crashes.
Well I actually tried my old world and removed ProjectRed... and it worked. Progress I guess. Now to figure out why ProjectRed is crashing my world.
I'm almost certain its the auto crafting bench. Looking through the mods items its the only item I used, and was using it both times my world crashed and wouldn't let me back in. The auto compressed cobble system I made was too big or simply messes up. Likely with a mixture of other things too, because I had those cobble makers for a whole day till they messed up my world. If that is the case. I'm going to say it was and play on my first world again!! I'll come back if it crashes again. I've added projectred back to my game and it works perfectly fine. I can't believe the world is back! For now at least.
I'll be honest the reason I figured it was ProjectRed was because the server crash log. I play on single player, so I figured the client log was the one I should post. Just incase this might help people in the future I will post the crash log that had server next to it rather then client.
