I believe I posted this topic in the wrong forum so I shall post it again.

Hello, I am getting an error when trying to load into a personal modpack of mine. It's been giving this error ever since I started working on adding mods again, and I don't know what's causing it. I don't have a crash report since it is merely me getting kicked from my singleplayer world but I do have the error from the logs. I can provide the full log and debug.log on mclogs or pastebin if required.

Please share the debug.log on pastebin, instructions are on the FAQ

I attempted to and it said "You have exceeded the maximum size of 512 kilobytes per Paste." The debug.log is 5MB. is there anywhere else I can upload it?

Edit 1: I checked the FAQ and saw Paste.ee. Will be posting the link shortly.

Edit 2: Here is the link. https://paste.ee/p/lwXY2. May not have my full list of mods installed because I was testing removing a few that seemed suspicious, i'm assuming it's an incompatibility with BYG and some other mod. Removing BYG is not an option, as it is one of my favorite mods.

Did you ever find the mod, I am building a large mod pack, and am having this exact error, but I dont know which mod it is?
Thanks
