I play hard mode, this bug has it so; commonly endermen will attack you even without looking at them, it happens in the end, nether and overworld which can be extremely problematic, like while killing the enderdragon you'll be attacked for no reason, if you're bridging in the end, you can get knocked into the void or lava in the nether and so on with many ways they just kill you due to endermen being agrro with no cause
