The player can't be null at runtime while ingame. If some mod is making it so, they need to learn how to not set everything on fire.

"this isnt my issue so i wont fix it" youre starting to sound like someone lol anyways thanks! luckily this isnt a recurring issue

So, some mod you have in that pack is making the mc player Minecraft.getMinecraft().player null, which doesn't make any sense, but I can't reproduce it with just AA.
