I added a bunch of new mods to my Minecraft a little while ago, and now I can't make a new world. The game never outright freezes, but it either stops processing things or takes an insanely long time to do so, and as far as I can tell the world generation makes no more progress. The log was too big for Pastebin, so I had to use a different site, but I have it here. Additionally, here's a screenshot of where the game stopped updating the loading screen. (Google Drive, by the way.) As far as I can tell, it's still trying to process things at the end, but either can't complete it or takes forever doing it. I waited on the DSODL (Dirt Screen of Death Lite; I've seen worse) for over half an hour with no visible progress made to be safe, since I know worlds can take a while to generate (especially with how many mods I have). From what little info I can gather, the cause might be Better Animals Plus, but I don't have any experience reading these logs, so I'm posing the question here, too: what should I do to fix this?

Ah, crap, there's a difference? Where do I find debug.log?

Must have overlooked it. I'm a bit preoccupied right now, but once I finish up I'll get that and reply again.

Okay, take two, everyone. Let's try this again. This one was too big for the other site and outright broke it, so this link is also Google Drive.

Is there anything I can do about this? I haven't had this problem before now.

Same thing I usually do, then. Gotcha. Thanks for this, and sorry I made you sift through that 7GB mess of a log to help.
