Hello i have been having a issue that when i create a new singleplayer world it just won't load and its stuck on preparing for world creation screen can someone help me?

Can you please post the full latest.log after spending at least 5-10 minutes "preparing for world creation"?

In my case, JVM ran out of memory. I had allocated 5408MB and the Java process was taking upwards of 7.9GB.
Here is my latest log file: latest.log

You can see in the log that it ran out of memory while registering recipes

Edit: Total time to crash after starting new world: approx. 17 min.

I'm facing the same issue.
Many JEI plugins seem to take a very long time to register recipes.

I'll post the full latest.log file once my game starts.

Do you have at least 16 GB of RAM on your computer? If so, try allocating at least 8 GB (8192 MB) to the game. If not, you won't be able to run the full pack.

Okay its working now thanks for the help

Thanks, Dobanek, raising memory fixed the issue.
