[Crash Log] Game Crash Upon Loading Old Minecraft Save

Game crashes when I try to load an old save trying to recreate a modpack. This should explain it all. https://pastebin.com/LSVMZgBh

Looks like an incompatibility with pixelmon, or one of these mods was not made for the minecraft version you're using.
