I don't think it has anything to do with conflicting mods, as I removed all of the mods besides the 2 that cause me issues before and didn't get anything. I did get in touch with LDshadowlady and she was wondering how I was getting the issue, because she said she couldn't get the issue to happen. I'm running 1.12.2 forge (1.12.2 14.23.5.2847) and the mods that I can't use are the Monsters&Pets (which seems to be causing the issue) and the Disney mod, which needs Monsters&Pets to run normally. This is the link to the mods, to see if you can get the issue to occur for you.

I don't know if this is where I should post this, If not please redirect me to the proper thread for this.

Hello! I've been trying to re-download Pixelmon all day today. I had It on a payed server, which I no longer can afford so I wanted to download it for regular Minecraft. I've downloaded it twice now, along with downloading optifine and forge twice now too. Everytime I try and load up the game, it crashes immediately. Any help is much appreciated, and I already added more RAM so that is not an issue.

// Uh... Did I do that?
